(x-2)(x+1)<0
x<2 or x<-1

(x-3)(x+1)
x<3 or x<-1
??

a is sufficient

b states that x^2<4
x<2 but nothing about x<-1
Insufficient.

A

x^2 - 4x + 3 < 0
i.e (x-3) (x-1) <0???
for this to be true 1<x<3 must be true.

St1: x^2 - 3x + 2 < 0
i.e (x-2)(x-1) < 0 means 1<x<2: SUFF

St2: x^2 < 4 means -2<x<2: INSUFF
