Can you factor out or not ??

OpenStudy (anonymous):

factorize numerator and denominator of each fraction,then cancel common terms

OpenStudy (anonymous):

yes i can but i get confused when its just 2 numbers like 45a+135 or 3a-6 is that already factored?

OpenStudy (anonymous):

no,ther's a common factor,if the terms contain numbers then the common factor is their GCD so for 45 and 135 its 15 and for 3 and 6 its 3
