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

Answer

The polynomial generated from the given zeros is: $P (x) = 6 x^{3} + 13 x^{2} + 9 x + 2$

Explanation

Step 1: Turn the zeros into factors:

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

Step 2: Multiply the factors together:

P (x) = (3 x + 2) \cdot (2 x + 1) \cdot (x + 1) = 6 x^{3} + 13 x^{2} + 9 x + 2
