Question

What is a cubic polynomial function in standard form with zeros -4, -5, and 4?

2 Answer

  • Hope it cleared your doubt.
  • The cubic polynomial function for the given zeroes is x³ + 5x² - 16x - 80.

    Given, x = -4, -5, and 4 are the zeros of the cubic polynomial.

    What is a cubic polynomial?

    A cubic polynomial is a polynomial that has highest degree of the variable 3.

    Therefore, this cubic polynomial is satisfied by all three values of x given above.

    Hence, the cubic polynomial will be:

    (x + 4)(x + 5)(x - 4)

    = (x + 4)(x - 4)(x + 5)

    = (x² - 16)(x + 5)

    = x³ - 16x + 5x² -80

    = x³ + 5x² - 16x - 80
