Find the polynomial having roots at $- \frac{1}{4}$ , $2$ and $- 3$ .

Answer

The polynomial generated from the given zeros is: $P (x) = 4 x^{3} + 5 x^{2} - 23 x - 6$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$- \frac{1}{4}$	$4 x + 1$
$2$	$x - 2$
$- 3$	$x + 3$

Step 2: Multiply the factors together:

P (x) = (4 x + 1) \cdot (x - 2) \cdot (x + 3) = 4 x^{3} + 5 x^{2} - 23 x - 6
