Find the polynomial having roots at $1$ , $- 2$ , $- 3$ and $4$ .

Answer

The polynomial generated from the given zeros is: $P (x) = x^{4} - 15 x^{2} - 10 x + 24$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$1$	$x - 1$
$- 2$	$x + 2$
$- 3$	$x + 3$
$4$	$x - 4$

Step 2: Multiply the factors together:

P (x) = (x - 1) \cdot (x + 2) \cdot (x + 3) \cdot (x - 4) = x^{4} - 15 x^{2} - 10 x + 24
