Factor 28-12x

myininaya (myininaya):

4(7-3x)

jimthompson5910 (jim_thompson5910):

The GCF of 28 and -12x is 4. So factor out the GCF to get 28-12x = 4(7-3x)

will that eb teh same as -4(3x-7)

myininaya (myininaya):

-4(-7+3x) -4(3x-7) yes :)

jimthompson5910 (jim_thompson5910):

yes those are the same

thanks i take it either response will be correct? This teacher likes to mindfreak us badly man....

jimthompson5910 (jim_thompson5910):

I'd stick with the first one since the GCF is positive and I usually see positive GCFs being factored out.
