Find the polynomial having roots at $- 2$ , $- \frac{2}{3}$ and $0$ .

Answer

The polynomial generated from the given zeros is: $P (x) = 3 x^{3} + 8 x^{2} + 4 x$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$- 2$	$x + 2$
$- \frac{2}{3}$	$3 x + 2$
$0$	$x$

Step 2: Multiply the factors together:

P (x) = (x + 2) \cdot (3 x + 2) \cdot x = 3 x^{3} + 8 x^{2} + 4 x
