Solve for x: x+4=4√(x+1)
x%2B4+=+4%2Asqrt%28x%2B1%29
%28x%2B4%29%2F4+=+sqrt%28x%2B1%29
%28x%2B4%29%5E2%2F16+=+x%2B1
%28x%5E2%2B8x%2B16%29%2F16+=+x%2B1
%281%2F16%29x%5E2%2B%281%2F2%29x%2B1+=+x%2B1
%281%2F16%29x%5E2-%281%2F2%29x%2B1+=+1
%281%2F16%29x%5E2-%281%2F2%29x+=+0
x%28%281%2F16%29x-%281%2F2%29%29+=+0
x = {0, 8}
