Question 838582: Subtract the polynomials.
8x^3+x^2+1 from 3x^3-x-6
I've tried it twelve times on webassign and asked on here previously, but the answer I was given was incorrect. I continued to try and I'm still not getting it.
This was the answer I was previously given: -5x^3 -x^2 -x - 7.

I've got it down to (subtracting vertically):
3x^3 -x -6
-8x^3 -x^2 -1

Thank you for your help!
