Not sure about remainder theorem but I'm sure that the last terms should all multiply tho the last term
see the expanded form is -45
so the last terms of each binomial should multiply to -45
3 times -5 times ?=-45
-15 times ?=-45
divide by -15
?=3
the question mark is 3
12 +4m = 24
4m = 12
m = 12/4
m = 3 so choice C. is right sure
You have to use distributive property.<span />
