-2x^2=-4x.

(-5x^2+4x^3)=(-25x+64x).

-4x(-25x+64x)=100x-256x.

100x-256x=-156x

-156x is your final answer.

- 8
x^(5) + 10
x^(4)

distribute the parenthesis by - 2x²

= 10
x^(4) - 8
x^(5)

= - 8
x^(5) + 10
x^(4) ← in standard form

Note that a polynomial expressed in standard form

The first term is the term with the highest exponent followed by the other terms in descending order of exponents
