Homework Help: Easy algebra problem

  1. Aug 26, 2010 #1
    1. The problem statement, all variables and given/known data

    P + N =C + 2/C

    solve for C

    2. Relevant equations

    I have tried all algebraic methods I can think of and can't solve for C.

    3. The attempt at a solution

    I ended up with C(N + P) = C^2 + 2

    Write it as C^2-C(N+P)-2=0. It's a quadratic equation in C, right? How do you solve quadratics?

    Oh okay, I use the quadratic formula. I understand now thanks!
