Question 460972: Factor out the greatest common factor:
5a(a+3b)+4/(a+3b)
I know I need to use (a+3b), just not sure how to do it when one of the terms is a fraction with a binomial in the denominator. Could this be a typo from the professor?

very likely
(5a^3+30a^2b+45ab^2+4)/(a+3 b)
as it is written
mu guess is it should be
5a(a+3b)+4(a+3b)
(5a +4)*(a+3b)
