c use g(x) as your x in f(x) d g(x) multiplied by h(x) e g(x) divided by f(x)
let me know where you get stuck
c. 2(x^2 - 4) + 7 d.10x^2-20x e. im not sure how to do that? are the other 2 correct?
c. need to simplify expand the parenthesis and group like terms
would c be 2x^3+7x^2-8x-28?
d. 10x^3-20x ?
or c would be 2x^3+7x^2-8x-21
for d you do not have 2x it is x^2 that 2 is a power means x multiplied by x
d. 5x^3-20x ?
would e just be (x2-4)/(2x+7) ? or can that be simplified
I think we should leave it like
thank you so much for your help
you are welcome
