By looking for common factors between the terms, starting with the numbers and then moving onto the letters, and then taking out these common factors.
The common factor of 3 & 12 is 3;
The common factor of a and a is a
There is no common factors with b.
Putting the common factors together results in 3a to take out:
3a x 1 = 3a
3a x -4b = -12ab
Thus 3a - 12ab = 3a(1 - 4b)
It is: 3a(1-4b)
12ab
1 x1 =1 2x2=4 and it goes on and on bye see you later
6a²b - 12ab²
34
It is 3a(a+3) when factored
It is: 3a(2b -3c) when factored
It is: 5(3a+b) when factored
12ab+3ab=15ab
2a2b2+3a2b2-5abc
2x5x8
yes!!!!!!!!!!!!!
