Question

Which equation has solutions of 6 and -6?

Answer 1

x^2-36=0

Explanation:

x^2-36=0

(x-6)(x+6)

Answer 2

`x^2-36=0`

Explanation:

Solution is 6 and -6. Lets check with each option

`x^2-12x+36=0`

`(x-6)(x-6)=0`

x-6=0 so x=6

Solutions are 6 and 6. First option does not gives us solution 6 and -6

`x^2+12x-36=0`. It is not factorable

`x^2+36=0`. It is not factorable

`x^2-36=0`

`(x+6)(x-6)=0`

x-6=0 , so x=6

x+6=0, so x=-6

`x^2-36=0` is the final answer
