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.

Answer:
7m-3x-1
10x+26
7x-12
Step-by-step explanation:
3m - 1 + 4m -3x
sum terms by the same variable:
3m+4m=7m
we have:
7m-3x-1
7(3+2x)-4x+5
apply the distributive property:
7*3+7*2x-4x+5
we have:
10x+26
3x+4(x-3)
apply the distributive property:
3x+4*x-12
we have:
7x-12
I am not sure, but I checked my answer and I am right. Hope this helps, thank you :) !!
