At-Home STAR, AR & ADAP Practice Test Cheat Sheet
- Quadratic Formula - A go‑to method for solving any quadratic equation of the form ax² + bx + c = 0. Simply plug your a, b, and c into x = (-b ± √(b² - 4ac))❄(2a) and watch the magic happen. Practice with different values to see how the roots change! OpenStax Elementary Algebra Key Concepts
- Properties of Exponents - Master rules like the product rule (a❿ * aᵝ = a❿❺ᵝ) and power rule ((a❿)ᵝ = a❿·ᵝ) to simplify any expression with powers. These shortcuts save tons of time and keep your work neat. Start combining and breaking down exponents until it feels second nature! OpenStax Prealgebra Key Concepts
- Laws of Sines and Cosines - Perfect for tackling non‑right triangles by relating sides and angles in flexible ways. Use the Law of Sines when you know two angles and a side, or the Law of Cosines for two sides and the included angle. Plot a triangle on graph paper and verify your answers to build intuition! OpenStax Algebra & Trigonometry Key Concepts
- Inverse Functions - If f(x) maps inputs to outputs one‑to‑one, its inverse f❻¹(x) flips the process, swapping roles of x and y. To find it, rewrite y = f(x), switch x↔y, then solve for y. Test by plugging f❻¹(f(x)) to ensure you get back the original x! OpenStax Intermediate Algebra Key Concepts
- Logarithmic Functions - The secret weapon for solving equations where the variable hides in the exponent. Remember: log(b) answers "To what power must a be raised to get b?" Practice by converting between exponential and log forms to deepen understanding. OpenStax Intermediate Algebra Key Concepts
- Factoring Polynomials - Break down complex polynomials into products of simpler terms to solve equations and simplify expressions. Start with common factors, then tackle trinomials and difference of squares. Factoring transforms messy problems into manageable steps! OpenStax Prealgebra Key Concepts
- Graphing Quadratic Equations - Quadratics graph as parabolas - find the vertex, axis of symmetry, and intercepts to sketch them perfectly. The vertex formula (−b/2a, f(−b/2a)) pinpoints your turning point. Practice shifting a, b, and c to see how the parabola stretches and moves! OpenStax Elementary Algebra Key Concepts
- Polar Coordinates - Represent points by (r, θ) instead of (x, y), where r is the radial distance and θ the angle from the positive x‑axis. Convert back and forth using x = r cosθ, y = r sinθ to master both systems. Polar plots make circular patterns and spirals a breeze! OpenStax Algebra & Trigonometry Key Concepts
- Parametric Equations - Express x and y as functions of a third variable (often t), giving a dynamic description of curves and motion. Perfect for modeling projectile paths, cycloids, or any time‑dependent trajectory. Sketch each point step by step to visualize how t traces the curve! OpenStax Algebra & Trigonometry Key Concepts
- Key Algebra Terms - Get comfortable with vocabulary like coefficient, variable, and exponent - your secret math power tools. In 7x², 7 is the coefficient, x the variable, and 2 the exponent. A solid grasp of terms makes complex topics feel like simple puzzles! LearnTheta: Key Algebra Terms
