Solve for:
√(x-7) / √(x) -2 = √2
My attempt at a solution:
I solved for x and it comes out to:
0 = x^2 - 64x +225
and then i plugged it into the quadratic formula:
[-(-64)±√((64)^2-4(1)(225))]/2
and my answer comes out to be:
32±√799
although the answer on the back of the package is 9 and 25.
kind of confused on how to attempt this question now and not sure what I'm doing wrong...
And thanks in advance for the help!
