Solve for x:
x-10sqrt%28x%29%2B9+=+0 Rewrite this to look like a quadratic equation in sqrt%28x%29
%28sqrt%28x%29%29%5E2-10%28sqrt%28x%29%29%2B9+=+0 Factor.
%28sqrt%28x%29-1%29%28sqrt%28x%29-9%29+=+0 Apply the zero product rule:
sqrt%28x%29-1+=+0 or sqrt%28x%29-9+=+0 so that...
sqrt%28x%29+=+1 or sqrt%28x%29+=+9 Square both sides of these two solutions.
