Solve for x: 2x + 3 = 11.
x = 3
x = 6
x = 4
x = 5
Subtract 3 from both sides to obtain 2x = 8. Dividing both sides by 2 yields x = 4, which is the correct solution.
Simplify the expression: 3x - 2x.
5x
x - 2
6x
x
Combine like terms by subtracting the coefficients: 3x - 2x equals x. Therefore, the simplified expression is x.
Evaluate the expression: 4(2) + 3.
8
10
11
7
First, multiply 4 by 2 to get 8, then add 3 resulting in 11. Thus, 11 is the correct answer.
Find the value of x if 5x = 20.
2
20
5
4
Divide both sides of the equation by 5 to isolate x. This gives x = 20/5 = 4, which is the correct solution.
If a = 3, what is the value of 2a + 4?
10
9
11
12
Substitute a = 3 into the expression: 2(3) equals 6, and adding 4 gives 6 + 4 = 10. Therefore, the correct answer is 10.
Solve for x: 3x - 5 = 2x + 4.
x = 8
x = 11
x = 10
x = 9
Subtract 2x from both sides to get x - 5 = 4, and then add 5 to both sides, yielding x = 9. This is the correct solution.
Simplify the expression: 2x + 3x - 4.
5x - 4
2x - 4
5x + 4
5x
Combine like terms by adding 2x and 3x to get 5x, then subtract 4 to achieve 5x - 4. This is the correct simplification.
Factor the quadratic expression: x^2 + 5x + 6.
(x + 1)(x + 6)
(x + 2)(x + 3)
(x + 3)(x + 4)
(x + 1)(x + 2)
The numbers 2 and 3 multiply to 6 and add to 5, so the quadratic factors as (x + 2)(x + 3). This factorization is correct.
Find the solution for x in the equation: x/2 + 3 = 7.
8
10
6
7
Subtract 3 from both sides to obtain x/2 = 4, then multiply by 2 to find x = 8. This is the correct method and solution.

13
10
11
12
Substitute x = 4 into the function f(x) = 3x - 1 to get f(4) = 12 - 1 = 11. Therefore, 11 is the correct evaluation.
Simplify the expression: 2(x + 3) - 4.
2x - 2
2x + 3
2x + 2
2x + 4
Apply the distributive property to obtain 2x + 6, then subtract 4, resulting in 2x + 2. This is the correct simplification.
Solve for x: 7 - x = 3.
-4
4
3
10
Subtract 7 from both sides to get -x = -4, then multiply by -1 to find x = 4. This is the correct solution.
Determine the solution set for the inequality: 2x - 5 > 3.
x ≥ 4
x ≤ 4
x > 4
x < 4
Add 5 to both sides to obtain 2x > 8, then divide by 2 to get x > 4. This correctly represents the solution set of the inequality.
Find the solutions for x in the quadratic equation: x^2 - 4x - 5 = 0.
x = 4 and x = 1
x = 5 and x = -1
x = 4 and x = -1
x = 5 and x = 1
Factor the quadratic as (x - 5)(x + 1) = 0, which gives x = 5 and x = -1 as the valid solutions.
Solve the system of equations: 2x + y = 7 and x - y = 1.
x = 2, y = 3
x = 4, y = 3
x = 3, y = 1
x = 8/3, y = 5/3
Solve the second equation for y to get y = x - 1 and substitute into the first equation, yielding 2x + (x - 1) = 7. This simplifies to 3x = 8, and thus x = 8/3 and y = 5/3.
Solve the quadratic equation x^2 + 2x - 8 = 0 using the quadratic formula.
x = 2 and x = -4
x = 4 and x = -2
x = -2 and x = 4
x = 2 and x = 4
Using the quadratic formula, x = (-2 ± √(4+32))/2 = (-2 ± 6)/2, which gives x = 2 and x = -4. These are the correct solutions.
Simplify the rational expression: (x^2 - 9)/(x + 3).
x - 3
x^2 - 3
x + 3
(x - 3)/(x + 3)
Factor the numerator as (x - 3)(x + 3) and cancel the common factor (x + 3) with the denominator, leaving x - 3 as the simplified expression (with the condition x ≠ -3).
Simplify the expression: √50 - 2√2.
√2
7√2
2√2
3√2
Express √50 as 5√2 since 50 = 25×2, then subtract 2√2 to get (5√2 - 2√2) = 3√2, which is the simplified form.
A rectangle's length is twice its width. If the perimeter is 36, what are the dimensions of the rectangle?
Width = 4 and Length = 8
Width = 6 and Length = 12
Width = 5 and Length = 10
Width = 12 and Length = 6
Let the width be w and the length be 2w. The perimeter is 2(w + 2w) = 6w = 36, so w = 6 and the length = 12. These dimensions satisfy the given conditions.

Midterm Algebra 2 Review Cheat Sheet

  1. Master the quadratic formula - Quadratic equations can feel like a wild ride, but the formula x = (-b ± √(b² - 4ac)) / (2a) gives you the roadmap to their roots. By checking the discriminant (b² - 4ac), you'll instantly know if you have two real solutions, one real solution, or a pair of complex conjugates. Practice makes perfect, so solve a variety of quadratics to see this tool in action! OpenStax Intermediate Algebra - Quadratic Formula
  2. Understand exponent rules - Exponents let you scale numbers up or down super quickly, and knowing the product, quotient, and power rules helps you simplify like a boss. Remember that a^m * a^n = a^(m+n), a^m / a^n = a^(m - n), and (a^m)^n = a^(m·n). Tackle a mix of practice problems to see how these rules save you time and effort. LearnMathClass: Exponent Rules
  3. Grasp functions and graphs - A function is basically a fancy machine that spits out one output for each input, and visualizing it on a graph helps you predict its behavior. Get cozy with linear lines, parabolic curves, and exponential rises so you can sketch them quickly. Charting these gives you insight into intercepts, slopes, and long‑term trends. OpenStax Algebra & Trigonometry - Functions
  4. Solve systems of equations - Whether you choose substitution, elimination, or graphing, finding where lines or curves intersect is a must‑have skill. Substitution swaps one variable for another, elimination adds or subtracts equations to cancel a variable, and graphing gives you a visual checkpoint. Mix and match these methods until you find your go‑to strategy. OpenStax Intermediate Algebra - Systems of Equations
  5. Explore logarithm properties - Logarithms are the coolinverse of exponentials, helping you solve equations where the unknown is in an exponent. Use the product rule log_b(xy) = log_b(x) + log_b(y), quotient rule log_b(x/y) = log_b(x) - log_b(y), and power rule log_b(x^n) = n·log_b(x). With these, you can break apart or combine logs like a puzzle master. LearnMathClass: Logarithm Properties
  6. Master sequences & series - Sequences are ordered lists of numbers, and series are the sums of those lists - get friendly with arithmetic and geometric types. Arithmetic sequences change by a fixed difference, while geometric sequences multiply by a constant ratio. Memorize the formulas for the nth term and the sum to breeze through problems. OpenStax Intermediate Algebra - Sequences & Series
  7. Use distance & midpoint formulas - In coordinate geometry, the distance d = √((x₂ - x₝)² + (y₂ - y₝)²) finds how far apart two points are, and the midpoint M = ((x₝+x₂)/2, (y₝+y₂)/2) spots the exact center. These handy formulas make plotting and proving shape properties a breeze. Practice with different point pairs to build confidence. OpenStax Algebra & Trigonometry - Distance & Midpoint
  8. Solve absolute value equations - Absolute value measures the distance from zero, so |x| = a splits into x = a and x = - a. When you tackle inequalities like |x| < a or |x| ≥ a, break them into two cases and watch the solution set unfold. These steps ensure you capture every valid solution. OpenStax Intermediate Algebra - Absolute Value
  9. Understand complex numbers - When equations refuse real solutions, you call on imaginary unit i, where i² = - 1, to build complex numbers in the form a + bi. Adding, subtracting, and multiplying these follows extended real‑number rules - just don't forget that i² = - 1! Embrace them to solve every stubborn quadratic. OpenStax Intermediate Algebra - Complex Numbers
  10. Apply the binomial theorem - Expanding (a + b)^n by hand gets easier with binomial coefficients, which come straight from Pascal's triangle or the formula n! / (k!·(n - k)!). Each term reveals combinations of a^(n - k)·b^k, so you can expand high powers without losing your mind. Use this theorem for quick polynomial growth and patterns. LearnMathClass: Binomial Theorem
