Answer:

  • f(x) = x⁴ - 11x³ + 25x² - 11x + 24

---------------------------------

It is assumed the provided numbers are the zero's of the polynomial function.

We know complex zero's come in pairs if function has rational constants.

So we should have zero's: 8, 3, -i and i.

Find the polynomial:

  • f(x) =
  • (x - 8)(x - 3)(x + i)(x - i) =
  • (x² - 11x + 24)(x² + 1) =
  • x⁴ - 11x³ + 25x² - 11x + 24
