Solve for x in the equation x^2 + 20x + 100 =36

x1 = -4, x2 = -16

Step-by-step explanation:

1.- equal the equation to 0

x^2 + 20x + 100 - 36 = 0

x^2 + 20x + 64

2.- factor to simplify.

(x + 4)(x + 16) = 0

3.- equal each factor to 0 and solve for x.

x + 4 = 0,   x = -4

x + 16 = 0,   x = -16
