(-2ab) (a^2b - 3ab^3)*

Answer 1

Respuesta:

$\mathrm{Expandir}\:\left(-2ab\right)\left(a^2b-3ab^3\right):\quad -2a^3b^2+6a^2b^4$

Explicación paso a paso:

$\left(-2ab\right)\left(a^2b-3ab^3\right)$

$\mathrm{Poner\:los\:parentesis\:utilizando}:\quad \:a\left(b-c\right)=ab-ac$

$a=\left(-2ab\right),\:b=a^2b,\:c=3ab^3$

$=\left(-2ab\right)a^2b-\left(-2ab\right)\cdot \:3ab^3$

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

$=-2a^3b^2+6a^2b^4$
