Answer:
4 is a factor. Also, (3n - 5) is a factor.
The factored form of 12n - 20 is:
4(3n - 5)
Step-by-step explanation:
We're looking for the biggest number (sometimes its a variable with the biggest exponent, but not this time)
that goes into 12n and also goes into 20. 4 is the biggest number that goes into both 12n and 20. So we factor it out...this is like "un-distributive property" (if you have been studying distributive property, this is like reversing it)
12n - 20
= 4(3n - 5)
