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
