Answer 4

Okay distribute the negative sign:
4x^2−2x−1+−1(−3x^3+2)
4x^2+−2x+−1+−1(−3x^3)+(−1)(2)
4x^2+−2x+−1+3x^3+−2
then combine the like terms
4x^2+−2x+−1+3x^3+−2
(3x^3)+(4x^2)+(−2x)+(−1+−2)
3x^3+4x^2+−2x+−3
Basically the answer for numebr one would be 3x^3+4x2−2x−3

Answer 5

For number two I got f^2xf^4=f^6 same thing
