(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

find f(a+h)-f(a)/h for the f (x)= 2x+3x^{2}

2. Relevant equations

f(a+h)-f(a)/h

3. The attempt at a solution

f(a+h)-f(a)/h

=2(a+h)-3(a+h)^{2}-2x+3x^{2}

=2a+2h-3a^{2}-3h^{2}-2a+3a^{2}

=2h-3h^{2}/h

that is where i am stuck

help please
