Can someone please help me with this math problem? Thanks.

Let g(x)=x^2-5 and h(x)=3x+2. Perform the function operation.

-2g(x)+h(x)

That would be

-2x^2 +10 + 3x +2 = -2x^2 + 3x +12.

oh, thanks! I understand.

I have another problem I'm unsure of.

g(x)*h(x)

I got 9x^2+12x-1 as the answer. Is that right?

no

you will have to multiply the two functions

that is,

(x^2-5)*(3x+2)

expand and simplfy

3x^3+2x^2-15x-10?
