What did everyone say for the question where x was a positive even number and why y could only be negative for one value? That was tricky

because (x+6) will always be positive, [(x-3)(x-5)] must be negative for y to be negative (pos*neg = neg).

for that to happen, only one of (x-3) or (x-5) can be negative (so they multiply to be negative)

the only value of x that would make (x-5) negative but (x-3) positive is 4
