Use this x+=+%28-b+%2B-sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
for ax%5E2+%2Bbx+%2B+c+=0
x+=+%28-3+%2B-+sqrt%28+3%5E2-4%2A1%2A%28-18%29+%29%29%2F%282%2A1%29+
+x+=+%28-3+%2B-+sqrt%2881%29%29%2F3
x+=+%28-3+%2B-+9%29%2F3
x+=+%28-1+%2B-+3%29
x = -1 + 3 or x = -1 -3
x =2 or x=-4

For x^2 + 3x - 18 = 0, we can see that it is factorable, so that we get
(x + 6)(x - 3) = 0
Thus
x = -6 or x = 3
