You are basically just adding, so combine like terms.

3x^2 + 5x^2 = 8x^2

6x - 2x = 4x

4 - 8 = -4

So the answer is D.

The expression for [tex] (f+g)(x) [/tex] is simply the sum of the expressions of [tex] f(x) [/tex] and [tex] g(x) [/tex].

So, you have

[tex] (f+g)(x) = f(x) + g(x) = (3x^2-2x+4)+(5x^2+6x-8) = 8x^2+4x-4 [/tex]
