Learn how to solve integrals of polynomial functions problems step by step online. Find the derivative of x^2-3x5x+-15 using the definition. Combining like terms -3x and 5x. Find the derivative of x^2+2x-15 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 x^2+2x-15. Substituting f(x+h) and f(x) on the limit, we get. Expand \left(x+h\right)^2. Multiply the single term 2 by each term of the polynomial \left(x+h\right).
