Learn how to solve integral calculus problems step by step online. Find the derivative of (21x^2+15x)/(-3x). Simplifying. Apply the quotient rule for differentiation, which states that if f(x) and g(x) are functions and h(x) is the function defined by {\displaystyle h(x) = \frac{f(x)}{g(x)}}, where {g(x) \neq 0}, then {\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}. Simplify \left(-x\right)^2. Simplify the product -(7x^2+5x).
