If (m-8) is a factor of m^2-jm-24, then j=

A 3
B 5
C 6
D 11
E 16

I've just passed Knewton's CAT and failed the question.
Frankly, I do not like the way Knewton explains this task and want to see how you crack it.


Given M-8 is a factor of the equation that means m=8 can be substituted in the equation to get j=5.
