HELP PLEASE ITS DUE TODAY!!!!!

Answer 1

Let's find.

$\\ \rm\Rrightarrow (-2x^3+x-5)(x^3-3x+4)$

$\\ \rm\Rrightarrow x^3(-2x^3+x-5)-3x(-2x^3+x-5)+4(-2x^3+x-5)$

$\\ \rm\Rrightarrow -2x^6+x^4-5x^3+6x^4-3x^2+15x-8x^3+4x-20$

$\\ \rm\Rrightarrow -2x^6+7x^4-13x^3-3x^2+19x-20$

#b

Yes

It's because multiplication law states that ab=ba
