  1. 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
