Question

- (3x
3 +-3 + 5x) por (7 + 2x)

Answer 1

Explicación paso a paso:

$=-\left(3x^3+\left(-3\right)+5x\right)\left(7+2x\right)$

$=-\left(3x^3-3+5x\right)\left(7+2x\right)$

$=-\left(3x^3\times \:7+3x^3\times \:2x-3\times \:7-3\times \:2x+5x\times \:7+5x\times \:2x\right)$

$=-\left(6x^4+21x^3+10x^2+29x-21\right)$

$=-6x^4-21x^3-10x^2-29x+21$
