Learn how to solve differential calculus problems step by step online. Find the derivative of 1/(x^2-4x+4)-1/4. 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 (-\frac{1}{4}) is equal to zero. Apply the quotient rule for differentiation, which states that if f(x) and g(x) are functions and h(x) is the function defined by {\displaystyle h(x) = \frac{f(x)}{g(x)}}, where {g(x) \neq 0}, then {\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}. The derivative of the constant function (1) is equal to zero.
