What is your book's (or teacher's) definition of "opposite"?

Not really sure, I just know one of the expressions is -(-7x^2+4)

I just need help figuring out the other one

Well, if you don't know what the book says, it's a pretty sure thing that I don't!

I'm sorry that your book has no examples or explanations, and that your teacher hasn't covered this at all. You might want to complain to the administration!

My guess (and that's all it is!)is that maybe you're supposed to multiply the "-" through the parentheses, and simplify. Good luck!
