How do you combine like terms in #(2p ^ { 2} + 5p + 11) + ( - p ^ { 2} - 9p - 4)#?

Answer:

#p^2-4p+7#

Explanation:

In short, when we combine terms, we need to look for terms with the same degree. We can rewrite the expression as

#color(blue)(2p^2-p^2)+color(purple)(5p-9p)+color(red)(11-4)#

I didn't change the value of the expression, I just grouped the like terms. We can simplify these to get

#color(blue)(p^2)color(purple)(-4p)+color(red)(7)#

Hope this helps!
