inequality... how does this make sense??
Solve (x-1)(x-2)<0
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??
