What´s is the solution for this inequality ((x-1)(3 - x)) /( x+2) > 0 ?
(x-1)(3-x)(x+2)\[>\]0 + + + + - - - - + - + -
there are 4 possibilities to satisfy above inequality as shown above.i.e 1. x-1>0 3-x>0 x+2>0 x>1 3>x x>-2 to satisfy all 3 conditions 1<x<3 2.x>1 3<x x<-2 no solutions for this ranges 3.x<1 3<x x>-2 -2<x<1 4.x<1 3>x x<-2 no solution therefore we have the range as -2<x<3 but x not equal to 1
