Question 170859
To find the GCF of {{{3m^2 - 6 + 9m}}}, simply think of it as the GCF of the terms {{{3m^2}}}, {{{-6}}} and {{{9m}}}.



So what do these terms have in common? They don't have "m" in common (since the term {{{-6}}} doesn't even have an "m" in it).



So we can safely eliminate the possibility of variables in the GCF




---------------------------------



Now let's move onto the coefficients: What do {{{3}}}, {{{-6}}}, and {{{9}}} have in common? Since the largest factor that is divisible by all 3 is 3, this means that the GCF is 3



=======================================


Answer:



So the GCF of {{{3m^2 - 6 + 9m}}} is 3. 



Note: this means that you can pull out the GCF and factor {{{3m^2 - 6 + 9m}}} to get {{{3(m^2 - 2 + 3m)}}}
