What are your thoughts?
Please share your work with us ...even if you know it is wrong.
If you are stuck at the beginning tell us and we'll start with the definitions.

“... mathematics is only the art of saying the same thing in different words” - B. Russell
Come on, we help with homework, that is we do not do it for you. For that you can hire an online tutor.
Before you can find (f-g)(x) you need to know the definition of (f-g)(x). You can't play the game unless you know the rules!
I'll give you the definition.
(f-g)(x) = f(x) - g(x). That is, just subtract the two functions. Can you go from here??
A mathematician is a blind man in a dark room looking for a black cat which isn’t there. - Charles R. Darwin
You've been given two polynomials and have been instructed to subtract and simplify. You've learned how to add and subtract polynomials and how to combine "like" terms. Please reply showing your set-up (with the two polynomials each in grouping symbols, with the "minus" sign between them), and your subtraction, specifying where you are getting stuck.
Thank you!
