Question

afectua la siguientes adiciones de forma horizontal a) (7x+8y) + (5x+4y)
b) (4a2b+5ab2) + (-8a2b+3a2b)​

Answer 1

Respuesta:

$\left(7x+8y\right)+\left(5x+4y\right)$

$=7x+8y+5x+4y$

$=7x+5x+8y+4y$

$=12x+8y+4y$

$=12x+12y$

$\left(4a^2b+5ab^2\right)+\left(-8a^2b+3a^2b\right)$

$=4a^2b+5ab^2-8a^2b+3a^2b$

$=4a^2b-8a^2b+3a^2b+5ab^2$

$=-a^2b+5ab^2$
