I need help with two algebra problems please!
What is (f+g)(x)?
f(x) = 8x^2 + 16x + 6
g(x) = x^3 - 3x^2 - 9
(f+g)(x)= ?
(multiplication)
what is (f x g)(x)?
f(x) = x^3 - 4x +2
g(x) = x^2 + 2
(f x g)(x)?
Thanks for the help!

fisrst one is just add the functions
(f+g)(x)=f(x)+g(x)=
8x^2+16x+6+x^3-3x^2-9=
(f+g)(x)=x^3+5x^2+16x-3
multiply
ok
f(x)g(x)=(x^3-4x+2)(x^2+2)
just multiply and expand yourself because I don't have my graphing calculator with me right now
