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
