    f'(x) of: f(x)= ax+b/(x-1)(x-4)

    Hey everyone, this is a grea tool a classmate of mine uses for his Calculus and I was wondering if you guys could help me with this assignment.

    I need to know how to take the f'(x) of: f(x)= ax+b/(x-1)(x-4) in a step by step format. I'm having trouble with this.

    Thanks

    Just use the quotient rule.

    \frac{ax+b}{x^{2}-5x+4}

    Quotient rule:

    \frac{(x^{2}-5x+4)(a)-(ax+b)(2x-5)}{(x^{2}-5x+4)^{2}}

    Now simplify
