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

Answer

The polynomial generated from the given zeros is: $P (x) = x^{4} + 3 x^{3} - 12 x^{2} - 20 x + 48$

Explanation

Step 1: Turn the zeros into factors:

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

Step 2: Multiply the factors together:

P (x) = (x - 2) \cdot (x - 2) \cdot (x + 3) \cdot (x + 4) = x^{4} + 3 x^{3} - 12 x^{2} - 20 x + 48
