there are lots of polynomial multiplication web sites. They will show you the workings if you have trouble. The first one is
2x^4 + x^3 - 18x^2 + 2x + 1
You try the other, and show us what happens if you get stuck.
Multiply polynomials just like multi-digit numbers, keeping each power of x in its own column, and no need to carry between columns.
Multiply the polynomials:
1. (x^2+3x-1)(2x^2-5x-1)
2. (2x-1)(x^4-3x^3+x2-5x+12)
