Best ResponseYou've already chosen the best response.1now "factor out" 4 from each term (this is the opposite of "distributing" ) for example if you had 2(x+1) you would do 2*x + 2*1 or 2x+2 to undo that we write 2x+2 as 2*x + 2*1 and then "take out" the 2 that is in both terms. that leaves (x+1) and we put the 2 out front: 2(x+1)

Best ResponseYou've already chosen the best response.1for your problem 4x+12 we first write it as 4*x + 4*3 now "take out" the 4 and put it "out front"

Best ResponseYou've already chosen the best response.1yes. as a check we can "distribute the 4" 4(x+3) = 4*x + 4*3 = 4x +12 which shows 4(x+3) means the same thing as 4x+12 we started with 4x+12 and "went backwards" and got 4(x+3)
