Specify the solving method
Apply the product rule for differentiation: $(f\cdot g)'=f'\cdot g+f\cdot g'$, where $f=2x+1$ and $g=x-1$
Learn how to solve product rule of differentiation problems step by step online.
$\frac{d}{dx}\left(2x+1\right)\left(x-1\right)+\left(2x+1\right)\frac{d}{dx}\left(x-1\right)$
Learn how to solve product rule of differentiation problems step by step online. Find the derivative using the product rule d/dx((2x+1)(x-1)). Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=2x+1 and g=x-1. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of a sum of two or more functions is the sum of the derivatives of each function. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=2 and g=x.
