    1/ ((t) (1 + 4t + 4t ^2)) + 4 / (1 + 4t + 4t ^2)


    = 5/ ((t) (1 + 4t + 4t ^2))

    No, it's not correct. To add these two rational expressions you need to find the least common denominator.

    Why are you posting these problems in the Calculus and Higher forum? They should go in the Precalculus forum.
