Question

Which is a solution to

(x - 2)(x + 10) = 13?
A. x = 3
B. x = 8
C. x = 10
D. x = 11

Answer 1

A,x=3

Explanation:

(x-2)(x+10)=13

x²+10x-2x-20=13

x²+8x-20-13=0

x²+8x-33=0

x²+11x-3x-33=0

x(x+11)-3(x+11)=0

(x+11)(x-3)=0

x=-11,3

Answer 2

A. x = 3

Explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

x=3
