Use the quadratic formula to solve for x

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

x+=+%28-%281%29%2B-sqrt%28%281%29%5E2-4%2810%29%28-3%29%29%29%2F%282%2810%29%29 Plug in a+=+10, b+=+1, c+=+-3

x+=+%28-1%2B-sqrt%281-%28-120%29%29%29%2F%2820%29

x+=+%28-1%2B-sqrt%281%2B120%29%29%2F%2820%29

x+=+%28-1%2B-sqrt%28121%29%29%2F20

x+=+%28-1%2Bsqrt%28121%29%29%2F20 or x+=+%28-1-sqrt%28121%29%29%2F20

x+=+%28-1%2B11%29%2F20 or x+=+%28-1-11%29%2F20

x+=+10%2F20 or x+=+-12%2F20

x+=+1%2F2 or x+=+-3%2F5
