Use quadratic formula to solve a function

  1. Jan 14, 2012 #1
    1. The problem statement, all variables and given/known data


    Use quadratic formula to solve for Lambda1 and Lambda2

    3. The attempt at a solution

    I took the equation inside the brackets and solved for L. It turned out that
    L1=Lambda1 and L2=Lambda2

    But when I plugged those findings back, I got a slightly different equation. Weird...

    Anyway, is that a right approach or am I missing something? You can see my full solution in the attachment.

    Thanks A LOT!

    What you have is not an equation, so you can't solve for anything.
    An equation has an = in it. That's how you know it's an equation. You don't have an equation.
