Q1)
From(1): (x-2)(x-3) = 0.
So, x=2 or x=3. We cannot tell the value of x for certainty
Not sufficient
From(2): x>0
Not sufficient
Both(1)&(2):
x=2, x=3 are bot greater than 0. So, still not sufficient

Hence, E

Q2) Similarly (x+1)(x+2) = 0.
So, x=-1 or x=-2
Using both statements, we still can't say whether x=-1 or x=-2

Hence, E

You should have posted this in DS section

Thanx
yes i realised that later on.
