y = (x+3)(x-2)(x+5), is x negative?
(1) y = 0
(2) x does not equal to 2
From statement 1:
If y equals 0, x should be -3, 2, or -5. x could be positive or negative.
From statement 2:
If x is not 2, x could be any number since y is not defined.
From statement 1 & 2:
If y equals 0 and x is not 2, x should be -3 or -5, both of which are negative.
I pick (C).
Auge um Auge, Zahn um Zahn !
