Just add them

Arrange the equation:

$3w^2 + 2w + 5w^2 - 7w$ after getting rid of parantheses

$=(3+5)w^2 + (2-7)w$

$=8w^2 -5w$

$=w(8w-5)$

Your answer is

$w(8w-5)$

$color(green)(=> w (8w - 5)$

$(3w^2 + 2w) + (5w^2 - 7w)$

$=> 3w^2 + 2w + 5w^2 - 7w, "after removing the braces"$

$=> 3w^2 + 5w^2 + 2w - 7w, " bringing like terms together"$

$=> 8w^2 - 5w, " Adding / Subtracting"$

$=> w * (8w - 5), " Taking common term out"$

What is (3w^2+2w) + (5w^2-7w)(3w^2+2w) + (5w^2-7w)?
