Find the polynomial having roots at $- \frac{1}{4}$ , $- \frac{1}{2}$ and $- 2$ .

Answer

The polynomial generated from the given zeros is: $P (x) = 8 x^{3} + 22 x^{2} + 13 x + 2$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$- \frac{1}{4}$	$4 x + 1$
$- \frac{1}{2}$	$2 x + 1$
$- 2$	$x + 2$

Step 2: Multiply the factors together:

P (x) = (4 x + 1) \cdot (2 x + 1) \cdot (x + 2) = 8 x^{3} + 22 x^{2} + 13 x + 2
