How do you solve square off?

The square of a number is the number, multiplied by itself. For example, the square of 5 is 5 x 5 = 25.You may also need to square an unknown number, like x2 = 25, solving for "x" in this case. In such a case, take the square root of both sides (with a calculator, if the number isn't a perfect square). In this case, the solution is 5. However, there are complications: minus 5 is also a solution.The square of a number is the number, multiplied by itself.
