x%5E4+%2B+8x%5E3+%2B+15x%5E2+-+2x+-+10+=+%28x%2B5%29%28x%2B1%29%28x%5E2+%2B+2x+-+2%29+=+0.
The roots from the linear factors are -5 and -1. The roots from the irreducible quadratic are x+=+%28-2+%2B-+sqrt%28+2%5E2-4%2A1%2A-2+%29%29%2F2+=+-1%2B-sqrt%283%29+ .







(Well, I saw this coming, hehe. I guess if you're a tutor you don't need any tutoring, do you?)
