Use the quadratic formula to solve for x

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

x+=+%28-%28-6%29%2B-sqrt%28%28-6%29%5E2-4%281%29%2836%29%29%29%2F%282%281%29%29 Plug in a+=+1, b+=+-6, c+=+36

x+=+%286%2B-sqrt%2836-%28144%29%29%29%2F%282%29

x+=+%286%2B-sqrt%28-108%29%29%2F2

x+=+%286%2Bsqrt%28-108%29%29%2F2 or x+=+%286-sqrt%28-108%29%29%2F2

x+=+%286%2B6i%2Asqrt%283%29%29%2F2 or x+=+%286-6i%2Asqrt%283%29%29%2F2

x+=+3%2B3i%2Asqrt%283%29 or x+=+3-3i%2Asqrt%283%29

The two solutions are x+=+3%2B3i%2Asqrt%283%29 or x+=+3-3i%2Asqrt%283%29
