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"#
