Polynomial Long Division Questions?

I have a problem checker, but I keep getting conflicting answers. Could someone please complete this problem, or hopefully both. I'm getting stuck at the very end with a possible remainder. Thanks! 1. (x-5x^2+10+x^3)/(x+2) 2. (9x^4-2-6x-x^2)/(3x-1) When I do it by hand, I get no remainders on... show more I have a problem checker, but I keep getting conflicting answers.

1. (x-5x^2+10+x^3)/(x+2)

2. (9x^4-2-6x-x^2)/(3x-1)

When I do it by hand, I get no remainders on either one. When I check the problem online, it gives me a remainder on both, so I'm desperate for a second opinion. Thanks so much!
