Learn how to solve sum rule of differentiation problems step by step online.

$\frac{d}{dx}\left(2x\right)+\frac{d}{dx}\left(-4\ln\left(x+2\right)\right)$

Learn how to solve sum rule of differentiation problems step by step online. Find the derivative (d/dx)(2x-*4*ln(x+2)) using the sum rule. The derivative of a sum of two functions is the sum of the derivatives of each function. The derivative of the linear function times a constant, is equal to the constant. The derivative of the linear function is equal to 1. The derivative of a function multiplied by a constant (-4) is equal to the constant times the derivative of the function.
