Answer:x=-2 and - 8
Step-by-step explanation:
X^2+10x+16=0
X^2+8x+2x+16=0
X (x+8) + 2 (x+8) = 0
(X+2) (x+8) = 0
X+2=0 and x+8=0
X=-2 and x=-8

(x + 8) (x + 2)
Step-by-step explanation:
Given
x² + 10x + 16
Consider the factors of the constant term ( + 16) which sum to give the coefficient of the x - term ( + 10)
The factors are + 8 and + 2, since
8 * 2 = 16 and 8 + 2 = 10, thus
x² + 10x + 16 = (x + 8) (x + 2) ← in factored form
