Question

squaring both sides​

Answer 1

Answer:

The square root of x, squared is x. There is one catch, though, and it is that you can only use this method when you only have the square root left on that side. For example, if your equation is sqrt(x+3) - 4 = 9? Then you would need to add a 4 to both sides before you can square both sides to free up your x.
