(1) M<0
(2) M^2+8M+12=0
The stimulus can be solved for M = -2 or M = -6
(1) does not clarify if it's M = -2 or M = -6 since both are negative.
(2) M^2+8M+12=0 can be factored into:
(M+2)(M+6) = 0, which also has the two solutions M = -2 and M = -6.
Even with both we cannot determine which answer is correct.
how did i miss that! i guess i was sleeping...
