Question

Write a polynomial function in it's factored form with zeros 5, -1, and 2

Answer 1

(x - 5)(x + 1)(x - 2) = 0

Explanation:

If a polynomial function has roots a, b, and c, then it is (x - a)(x - b)(x - c).

The roots here are 5, 1, and 2, so the factors are

(x - 5)(x - (1))(x - 2)

The function is:

(x - 5)(x + 1)(x - 2) = 0
