Solving Quadratic Equations: Factoring

Question 10 • FL-1200710-Mathematics for College Algebra A

For what values of x is x2 + 2x = 24 true?

Answer

–6 and –4

–4 and 6

4 and –6

6 and 4

Move 24 to the left to get x² + 2x − 24 = 0. Factor: (x + 6)(x − 4) = 0, so x = −6 or x = 4. Choice C, “4 and −6,” lists both values.
