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

Answer

The polynomial generated from the given zeros is: $P (x) = x^{4} + 5 x^{3} - 4 x^{2} - 44 x - 48$

Explanation

Step 1: Turn the zeros into factors:

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

Step 2: Multiply the factors together:

P (x) = (x + 2) \cdot (x + 2) \cdot (x + 4) \cdot (x - 3) = x^{4} + 5 x^{3} - 4 x^{2} - 44 x - 48
