5/(n^3=5n^2)=4/(n+5)+1/n^2

1. I assume you are solving 2. I assume that the = should be + (since they are on the same key) so 5/(n^3+5n^2)=4/(n+5)+1/n^2 5/(n^2(n+5)) = 4/(n+5) = 1/n^2 multiply both sides by n^2(n+5) 5 = 4n^2 + n+5 4n^2 + n = 0 n(4n+1) = 0 n = 0 or n = -1/4 but n cannot be zero because of the original last term so n = -1/4

thank you sooo much :)
