Question

(2a² - 3a) (-3a + 2a)

3x2 + 2(x2 - 4x²)

(16 + 2b + b) (4 -b)

(17am - 3a²m + 2m) (3am)

Answer 1

Respuesta:

(2a² - 3a) (-3a + 2a)

$=\left(2a^2-3a\right)\left(-a\right)\\\\=-\left(2a^2-3a\right)a$

3x2 + 2(x2 - 4x²)

$=6x+2\left(-4x^2+2x\right)\\\\=6x+2\left(2x-4x^2\right)\\\\=6x+4x-8x^2\\\\=10x-8x^2\\\\=-8x^2+10x$

(16 + 2b + b) (4 -b)

$=\left(3b+16\right)\left(-b+4\right)$

(17am - 3a²m + 2m) (3am)

$=\left(3am\right)\cdot \:17am+\left(3am\right)\left(-3a^2m\right)+\left(3am\right)\cdot \:2m\\\\=17am\left(3am\right)-3a^2m\left(3am\right)+2m\left(3am\right)\\\\=51a^2m^2-9a^3m^2+6am^2$
