Use the quadratic formula to solve for x

x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29

x+=+%28-%288%29%2B-sqrt%28%288%29%5E2-4%281%29%2812%29%29%29%2F%282%281%29%29 Plug in a+=+1, b+=+8, c+=+12

x+=+%28-8%2B-sqrt%2864-%2848%29%29%29%2F%282%29

x+=+%28-8%2B-sqrt%2816%29%29%2F2

x+=+%28-8%2Bsqrt%2816%29%29%2F2 or x+=+%28-8-sqrt%2816%29%29%2F2

x+=+%28-8%2B4%29%2F2 or x+=+%28-8-4%29%2F2

x+=+-4%2F2 or x+=+-12%2F2

x+=+-2 or x+=+-6

The two solutions are therefore: x+=+-2 or x+=+-6
