Solving Quadratic Equations: Factoring

Question 1 • FL-1200700-Mathematics for College Algebra MIS

Which are solutions of the equation (x + 5)(x – 3) = 0? Check all that apply.x = –15x = –5x = –3x = 2x = 3x = 5

Answer
A
x = –15
B
x = –5
C
x = –3
D
x = 2
E
x = 3
F
x = 5

Explanation

A product equals zero when at least one factor is zero. Set x + 5 = 0 to get x = −5, or set x − 3 = 0 to get x = 3. Thus the solutions are x = −5 and x = 3.
