Solve for x in the equation x^2 + 10x + 12 = 36. x = –12 or x = 2 x = –11 or x = 1 x = –2 or x = 12 x = –1 or x = 11

x=2 or x=-12

Step-by-step explanation: Subtract 12 to both sides of the equation: x² + 10x = 24. Subtract 24 to both sides of the equation: x² + 10x -24. Next, find out which two numbers multiply to -24 and add up to 10: 12 and -2.

X² + 12x + -2x -24.

X(x - 2) and 12(x - 2)

Solve for x: (x+12) and (x-2) = 0

X = -12 or x=2
