x2squared = 144

In order to solve this equation, we need to isolate the variable x.

Starting with x^2 = 144, we can take the square root of both sides to rid of the exponent:

√(x^2) = √144

This simplifies to:

x = ±12

So the possible solutions for x are 12 and -12.

so is it -12 or 12

The possible solutions for x in the equation x^2 = 144 are both -12 and 12.
