Question

Sumar los polinomios:1. (-a^2-3ab+b^2) +2.( 6a^2-12ab+b^2)+3.[-5ab+b^2(-a^2-3ab+b^2)+(-5ab+b^2)]

Answer 1

Explicación:

$(-a^2-3ab+b^2) +2.( 6a^2-12ab+b^2)+3.[-5ab+b^2(-a^2-3ab+b^2)+(-5ab+b^2)]$

$=(11a^2-27ab+3b^2)+3*[-a^2b^2-3ab^3-10ab+b^4+3b^2]$

$= (11a^2-27ab+3b^2)+(-3a^2b^2-9ab^3-30ab+3b^4+3b^2)$

$=-3a^2b^2+11a^2-9ab^3-57ab+3b^4+6b^2$
