The complex zeros of the polynomials are 20i and -20i
Given the polynomials, the zeros of the polynomial are gotten by equating the function to zero and then factorizing as shown:
f(x)=x^3−96x^2+400
x^3−96x^2+400 = 0
x^2(x-96) + 400 = 0
x^2(x - 96) = -400
x^2 = -400
Get the required complex roots:
x^2 = -400
x = ±√-400
x = ±20i
Hence the complex zeros of the polynomials are 20i and -20i
