Question

El resultado de (xy³+3x-y)(x³)

Answer 1

$\bold{Hola!}$

$\left(xy^3+3x-y\right)\left(x^3\right)$

$\left(x^3\right)\left(xy^3+3x-y\right)$

$\left(x^3\right)xy^3+\left(x^3\right)\cdot \:3x+\left(x^3\right)\left(-y\right)$

$xy^3\left(x^3\right)+3x\left(x^3\right)-y\left(x^3\right)$

$x^4y^3+3x^4-x^3y\Longrightarrow\boxed{RESPUESTA}$
