Answer:
part a = 4m(m2+3xm-2m-6x) part b = 4m(m+3x)(m-2)
Step-by-step explanation:
greatest common factor is 4m
divide all the factors by 4m to get asnwer to part a
next seperate both equations
4m(m(m+3x) - 2(m+3x))
= take m+3x out because same thing as one part of factored equation
remaining is m-2
write together to get 4m(m+3x)(m-2)
