Solve:
x%5E2%2B6x%2B6+=+0 Since this is not factorable, you can use the quadratic formula to solve for x:
x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a in this problem, a = 1, b = 6, and c = 6
x+=+%28-6%2B-sqrt%286%5E2-4%281%29%286%29%29%29%2F2%281%29 Simplify this.
x+=+%28-6%2B-sqrt%2836-24%29%29%2F2
x+=+%28-6%2B-sqrt%2812%29%29%2F2
x+=+%28-6%2B-2sqrt%283%29%29%2F2
x1+=+-3%2Bsqrt%283%29
x2+=+-3-sqrt%283%29
