Find and simplify the difference quotient for the given function
iren2701 [21]
\dfrac{f(x+h)+f(x)}{h}

Replace f(x) and f(x+h) by using the equation given for the problem.

=\dfrac{(2(x+h)^2-(x+h)-1)-(2x^2-x-1)}{h}

Open all parenthesis

= \dfrac{2x^2+4xh+2h^2-x-h-1-2x^2+x+1}{h}

Factor the h

= \dfrac{h(4x+2h-1)+2x^2-2x^2+1-1+x-x}{h}

Other terms not in the parenthesis cancel each other out

\dfrac{h(4x+2h-1)}{h}

Now, simplify

=4x+2h-1
