Question

The following points are zeros to a polynomial function {-3, -2. -1, and 2}. What is the polynomial function?

Answer 1

y = x⁴ + 4x³ + x² - 18x - 12

Explanation:

y = [(x+3)(x+2)][(x+1)(x-2)] = (x² + 5x + 6)(x² - x - 2) =

x⁴ - x³ - 2x + 5x³ - 5x² - 10x + 6x² - 6x - 12 =

x⁴ + 4x³ + x² - 18x - 12
