What is a quartic polynomial function in standard form with zeros 1, –2, –2, and –3?

Answer 1

I would guess at
y = (x-1)(x + 2)(x + 2)(x + 3)
or
y = 17(x-1)(x+3)(x+2)^2

It asked for one such function
expand it if you feel you must.

( placing a constant in front does not change the x-intercepts )
