%289%29%5E2%2B%28x-3%29%5E2=x
81%2Bx%5E2-6x%2B9=x
x%5E2-7x%2B90=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-7%29+%2B-+sqrt%28+%28-7%29%5E2-4%2A1%2A90+%29%29%2F%282%2A1%29+
x+=+%287+%2B-+sqrt%28+49-360+%29%29%2F%282%29+
x+=+%287+%2B-+sqrt%28+-311+%29%29%2F%282%29+
highlight_green%28x+=+%287+%2B-+sqrt%28+311+%29i%29%2F%282%29%29+
