If let's say we have the following expression
√(x^2 - y^2)
If I wanted to factor out x, then why can't I just take x out because a square root of a square is the base.
x√(1 - y^2)
But it turns out that the answer to this is incorrect and the answer to factoring out x is.
x√(1 - y^2/x^2)
Why is it I divide by y^2, by x^2 ? I have no idea! Thanks.
