Inequality how does this make sense?

  1. Mar 3, 2012 #1
    inequality... how does this make sense??

    1. The problem statement, all variables and given/known data

    Solve (x-1)(x-2)<0



    2. Relevant equations



    3. The attempt at a solution

    Given this is a parabola
    graphical solution
    cuts the x axis at 1 & 2
    therefore sltn....
    1<x<2

    However, in my textbook the answer says (1/√5)/2<x<(1+√5)/2
    Can someone please confirm this is the wrong answer
    Or AM I MISSING SOMETHING HUGE HERE??
