Which equation has solutions of 6 and -6? x2 – 12x + 36 = 0 x2 + 12x – 36 = 0 x2 + 36 = 0 x2 – 36 = 0

X^2 – 12x + 36 = 0
(x-6)(x-6)=0
x=6 x=6
Not a solution

x^2 + 12x – 36 = 0
Doesn't factor
Not a solution

x^2 + 36 = 0
x=√-36
Not a solution

x^2 – 36 = 0
(x-6)(x+6)= 0
x=6 x=-6
Solution

ANSWER: The equation with solutions of x=6 and x=-6 is the last choice: x^2 - 36= 0.

Hope this helps! :)
