$\frac{1}{1-z^2}\frac{d}{dx}\left(2x-1+z\right)$
Learn how to solve product rule of differentiation problems step by step online. Find the derivative using the product rule d/dx((2x-1z)/(1-z^2)). The derivative of a function multiplied by a constant (\frac{1}{1-z^2}) is equal to the constant times the derivative of the 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=. The derivative of the constant function (2) is equal to zero.
