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

x+=+%28-%28-8%29%2B-sqrt%28%28-8%29%5E2-4%281%29%28-17%29%29%29%2F%282%281%29%29

x+=+%288%2B-sqrt%2864-%28-68%29%29%29%2F%282%29

x+=+%288%2B-sqrt%2864%2B68%29%29%2F%282%29

x+=+%288%2B-sqrt%28132%29%29%2F2

x+=+%288%2Bsqrt%28132%29%29%2F2 or x+=+%288-sqrt%28132%29%29%2F2

x+=+%288%2B2%2Asqrt%2833%29%29%2F2 or x+=+%288-2%2Asqrt%2833%29%29%2F2

x+=+4%2Bsqrt%2833%29 or x+=+4-sqrt%2833%29
