Sample Questions and How to Use the Answer Key
Sample Question 1: Factoring a Polynomial
Factor the quadratic polynomial: \(x^2 + 5x + 6\)
Answer Key Solution: The factors are \((x + 2)(x + 3)\).
Use: After solving, compare your factored form with the answer key to confirm correctness. If you arrived at different factors, review the factoring process.
Sample Question 2: Solving a Logarithmic Equation
Solve for \(x\): \(\log_2(x) + \log_2(x - 3) = 3\)
Answer Key Solution: Using logarithm properties, combine to \(\log_2[x(x - 3)] = 3\). Then, convert to exponential form: \(x(x - 3) = 2^3 = 8\). Simplify to \(x^2 - 3x = 8\), then solve the quadratic: \(x^2 - 3x - 8 = 0\). The solutions are \(x = 4\) and \(x = -2\). Discard the negative solution since logarithms of negative numbers are undefined. Final answer: \(x = 4\).
Use: Confirm your solution matches the answer key; if not, review steps and properties used.
Tips for Success in Your Algebra 2 Final Exam 2023
