I'm slightly confused.

But Im not sure about the last one/: Im sorry. I hoped Ive helped at least a little bit.......
r(x)=2x^2
s(x)=4x

(r+s)(x)=?
(r-s)(x)=?
(r*s)(2)=?

Ok so when it asks r+s is means adding 2x^2 +4x. So you would have (r+s)(x)=2x^2+4x.
Then you subtract r and s. So you would have (r-s)(x)=2x^2-4x, because there are no like terms. But I'm not sure about the last one/: I'm sorry. I hoped I've helped at least a little bit.
