the answer is #(4m+3)(m-2)#

Explanation:

first you have to see what multiplies to give you #24# (from #4*6#) and then add up to give you #-5# in the middle and you get: #-8,3# then just substitute #-5# with those two numbers like so: #4m^2-8m+3m-6# then group them#(4m^2-8m)+(3m-6)#)and factor out to get your answer. make sure the numbers or answer in the parenthesis is the same with the other because then you know it's right
