Learn how to solve definition of derivative problems step by step online. Factor the expression 2x^2+ax. Find the derivative of 2x^2+ax using the definition. Apply the definition of the derivative: \displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}. The function f(x) is the function we want to differentiate, which is 2x^2+ax. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term x by each term of the polynomial \left(a+h\right). Multiply the single term -1 by each term of the polynomial \left(2x^2+ax\right). Simplifying.
