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 ${\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}$

$\frac{\frac{d}{dx}\left(x^3-2x^2-5x+6\right)\left(x+1\right)-\left(x^3-2x^2-5x+6\right)\frac{d}{dx}\left(x+1\right)}{\left(x+1\right)^2}$
Learn how to solve differential calculus problems step by step online. Find the derivative of h(x)=(x^3-2x^2-5x+6)/(x+1). 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 the product -(x^3-2x^2-5x+6). Simplify the product -(-2x^2-5x+6). Simplify the product -(-5x+6).
