Use the quadratic formula to solve for x

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

x+=+%28-%2816%29%2B-sqrt%28%2816%29%5E2-4%285%29%2812%29%29%29%2F%282%285%29%29

x+=+%28-16%2B-sqrt%28256-%28240%29%29%29%2F%2810%29

x+=+%28-16%2B-sqrt%2816%29%29%2F10

x+=+%28-16%2Bsqrt%2816%29%29%2F10 or x+=+%28-16-sqrt%2816%29%29%2F10

x+=+%28-16%2B4%29%2F10 or x+=+%28-16-4%29%2F10

x+=+-12%2F10 or x+=+-20%2F10

x+=+-6%2F5 or x+=+-2
