Answer:

x = ± 6

Step-by-step explanation:

To find x in an equation, isolate it. Whatever you do to one side, do to the other.  

In this case, we need to find the square root of both sides in order to have [tex]x^2[/tex] become [tex]x[/tex] and find the variable's value:

[tex]x^2 = 36\\\sqrt{x^2} =\sqrt{36} \\x =-6, 6[/tex]

The square root of 36 can be both -6 and 6. (Remember that when finding the square root of a positive number, it will have a negative and positive outcome.) So, x = -6 and 6.
