You can put this solution on YOUR website!
x(x-7)=30
x^2 - 7x - 30 = 0
(x-10)(x+3) = 0
x = 10 or x = -3

x%28x-7%29=30
then
+x%5E2-7x-30=0+
then
x+=+%28-%28-7%29+%2B-+sqrt%28+%28-7%29%5E2-4%2A%281%29%2A%28-30%29+%29%29%2F%282%2A1%29+
then
x+=%28+7+%2B-+sqrt%28+169+%29%29%2F2+
then
x+=+%287+%2B-+13%29%2F2+
then
x=-3 or x=10
