Question

a) 2x (x^2+3x1-3)
n) -9 (2x-1)
c) -y (2y+1)
d) (n-2) (n+3)

Answer 1

Resposta:

Explicação passo a passo:

$\mathrm{Simplificar}\:2x\left(x^2+3x^1-3\right):\quad 2x\left(x^2+3x-3\right)\\\\\mathrm{Simplificar}\:-9\left(2x-1\right):\quad -18x+9\\\\\mathrm{Expandir\:}-y\left(2y+1\right):\quad -2y^2-y\\\\\mathrm{Expandir\:}\left(n-2\right)\left(n+3\right):\quad n^2+n-6$
