Locating Zeros of Polynomial Function

Question 5 • IASD Precalculus 2nd Quarter - Wingerter 2025-26

A quadratic expression can be factored so that (x − 12)(x + 17) = 0. What are the solutions to the equation?

Answer
A
x = 12 or x = 17
B
x = −12 or x = 17
C
x = 12 or x = −17
D
x = −12 or x = −17

Explanation

By the zero-product property, if (x − 12)(x + 17) = 0, then either x − 12 = 0 or x + 17 = 0. Solving gives x = 12 or x = −17, so the correct choice is C, “x = 12 or x = −17.”
