$derivdef\left(2x^2+4x-5x\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of x^2+4x-5xx^2 using the definition. Combining like terms x^2 and x^2. Combining like terms 4x and -5x. Find the derivative of 2x^2-x 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-x. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term -1 by each term of the polynomial \left(x+h\right).
