if f(x) = x^(2) + 3x - 2, then find the following:

f(x+h)

i pluged in the numbers and got

(x+h)^ (2) + 3(x + h) - 2

now i'm stuck. i tried doin other things but it didnt work out. where do i go from here.

also

f(x+h) - f(x) / x

i pluged in the numbers for this one also and i'm stuck now

(x+h)^(2) + 3(x + h) - 2 - x^(2) + 3x - 2 / x

would i factor x ^(2) + 3x -2 first or what?
