$derivdef\left(256-717x\right)$
Learn how to solve problems step by step online. Find the derivative of 14x-12x39x-18x=256-60x-657x using the definition. Combining like terms -60x and -657x. Find the derivative of 256-717x 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 256-717x. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term -1 by each term of the polynomial \left(256-717x\right). Add the values 256 and -256.
