Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=x+y+z and g=x+y-z. 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. The derivative of the constant function (z) is equal to zero.
