Find the polynomial having roots at $- 3$ , $- 2$ , $2$ and $4$ .

Answer

The polynomial generated from the given zeros is: $P (x) = x^{4} - x^{3} - 16 x^{2} + 4 x + 48$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$- 3$	$x + 3$
$- 2$	$x + 2$
$2$	$x - 2$
$4$	$x - 4$

Step 2: Multiply the factors together:

P (x) = (x + 3) \cdot (x + 2) \cdot (x - 2) \cdot (x - 4) = x^{4} - x^{3} - 16 x^{2} + 4 x + 48
