$\frac{d}{dx}\left(xy\right)+\frac{d}{dx}\left(x\right)+\frac{d}{dx}\left(-2y\right)+\frac{d}{dx}\left(-1\right)$
Learn how to solve differential calculus problems step by step online. Find the derivative d/dx(xy+x-2y+-1) using the sum rule. 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=x and g=y. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=-2 and g=y. The derivative of the constant function (y) is equal to zero.
