Find the polynomial having roots at $- \frac{1}{2}$ , $- \frac{1}{3}$ , $- 1$ and $2$ .

Answer

The polynomial generated from the given zeros is: $P (x) = 6 x^{4} - x^{3} - 16 x^{2} - 11 x - 2$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$- \frac{1}{2}$	$2 x + 1$
$- \frac{1}{3}$	$3 x + 1$
$- 1$	$x + 1$
$2$	$x - 2$

Step 2: Multiply the factors together:

P (x) = (2 x + 1) \cdot (3 x + 1) \cdot (x + 1) \cdot (x - 2) = 6 x^{4} - x^{3} - 16 x^{2} - 11 x - 2
