<h3>hello!</h3>
In order to solve this equation, we need to take the square root of both sides (in order to get rid of the square and isolate x, because we are asked to determine the value(s) of x)
x²=36
√x²=√36
x=6
Is this the only solution?
<em>A negative times a negative is a </em><em>positive...</em>
-6 is another solution of this equation! :)
Hence, the answers are:-
Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
