Question 743350: Trying to solve 2*sqrt(x-3)=6
tried squaring both sides and came up with 2*x-3 = 6^2
that divided out to X=21
tried checking the answer but it does not work.
Is this equation not solvable?
Thank you..

You can put this solution on YOUR website!
2*sqrt(x-3)=6}}}
/2
sqrt%28x-3%29=3

square both sides
x-3=9
x=12
( when you have squared you have to square the 2also)
