3x al cuadrado + 12x al cuadrado=
-5ab+3ab=
xy a la 3 + 5 xy a la tres - 2xy a la tres=

Answer 1

Resolver.

3x² + 12x² =
(3 + 12)x² =
 15x²


- 5ab + 3ab =
(- 5 + 3)ab =
 - 2ab


xy³ + 5xy³ - 2xy³
(1 + 5 - 2)xy³ =
(6 - 2)xy³ =
4xy³

Answer 2

$3x^{2} +12 x^{2} = 15 x^{2}$

-5ab+3ab = -2ab

$xy^{3}+ 5xy^{3} -2x y^{3} = ( 1+5-2)xy^{3} = 4xy^{3}$
