What can you factor out of \(\sf3x-12\) ?
TheSmartOne (thesmartone):
Hint, if you want you can start with the answer choices.
If you do, use this to see if it expands to \(\sf3x-12\)
\(\sf\large a(b-c) = ab-ac\)

what goes into 3x and -12?
OpenStudy (daltonw):
the greatest common factor is 3
OpenStudy (acxbox22):
correct if we take 3 out of 3x we are left with x
if we take 3 out of -12 we are left with -4
so 3 goes outsdie of the parentheses and what is left goes inside the parentheses
OpenStudy (daltonw):
okay!! that helps! then what do you do?? (:
OpenStudy (daltonw):
is the answer something like this?\[3x(x-4)\]
