Homework Help: Help me factor please

  1. Jan 25, 2006 #1
    [tex]e^{2x} - 3e^{x + 1} + 2e^{2} = 0[/tex]

    I've been staring at this for the past while I can't solve it for x...

    The only thing I can think of doing is factoring out [itex]e^{x}[/itex]

    Try setting u=e^x. Then you'll have a quadratic equation for u.
