Question

(7x^2+5x^3y) + (-6x^2+7x^3y) + (4x^3y+x^2)

Answer 1

$\left(7x^2+5x^3y\right)+\left(-6x^2+7x^3y\right)+\left(4x^3y+x^2\right)$
$=7x^2+5x^3y-6x^2+7x^3y+4x^3y+x^2$
$\mathrm{Agrupar\:terminos\:semejantes}:$
$=5x^3y+7x^3y+4x^3y+7x^2+x^2-6x^2$
$\mathrm{Sumar\:elementos\:similares:}\:7x^2+x^2-6x^2=2x^2$
$=5x^3y+7x^3y+4x^3y+2x^2$
$\mathrm{Sumar\:elementos\:similares:}\:5x^3y+7x^3y+4x^3y=16x^3y$
=16x³y+2x²
