You can put this solution on YOUR website!
x=+sqrt%28880-8x%29
x%5E2=+880-8x
x%5E2%2B8x-880=0
Complete the square,
x%5E2%2B8x%2B16-880=16
%28x%2B4%29%5E2=896
x%2B4=0+%2B-+sqrt%28896%29
x=-4+%2B-+8%2Asqrt%2814%29
Now, your turn, verify the solutions using the original equation because only one of these is a valid solution.
