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.

Which is the extraneous solution of -x the square root of 2x 15?
The answer would probably be either -3 or 5
How do you solve The square root of x plus 5 equals 5 minus the square root of x?
call sqrtx n, then n + 5 = 5 - n, ie 2n = 0, so there's no solution other than the trivial 0.
How does square root work?
The idea is to find a number which, when square, equals the given number. For example, asking for the square root of 100 means solving the equation x2 = 100. The solution, in this case, is 10. (Minus 10 is also a solution, but the term "square root" refers to the positive solution in this case.)The idea is to find a number which, when square, equals the given number.
