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
