Adding and Subtracting Rational Expressions
there are two problems I get stuck with towards the end.
1) 5n/3 + 4n/3
5n+4n/3
9n/3
now i get stuck, i think that I must factor it more but i am unsure, my teacher said I incorrectly distribute the signs?
2) 7/x5  2+x/x5
for this one I get an answer of 1
1) 5n/3 + 4n/3 = 9n/3
9n/3 = 3n
2)7/(x5)  (2+x)/(x5) = (72+x)/(x5)
= (5+x)/(x5)
