Find the polynomial having roots at $1$ , $5$ and $3$ .

Answer

The polynomial generated from the given zeros is: $P (x) = x^{3} - 9 x^{2} + 23 x - 15$

Explanation

Step 1: Turn the zeros into factors:

Zero	Factor
$1$	$x - 1$
$5$	$x - 5$
$3$	$x - 3$

Step 2: Multiply the factors together:

P (x) = (x - 1) \cdot (x - 5) \cdot (x - 3) = x^{3} - 9 x^{2} + 23 x - 15
