    ok, it is (58/9) (x^2 +5)(x -4) if it is not that, I don't know how to solve it.

    please try this polynomial: \[\Large f\left( z \right) = k\left( {z - 3} \right)\left( {z - 4} \right)\left( {z - 5i} \right)\]

    you have to determine k, such that the subsequent condition holds: \[\Large f\left( { - 2} \right) = 116\] namely your condition

    he has only 2 roots, not 3, 3 is the degree of the polynomial @Michele_Laino

    One more thing: Although -5i is not stated out, but when we have 5i is a root, then, so as -5i, right?
