<span>I can be wrong, but I think that the answer is: To find the values of p, q, r and s, you should start by finding all factor pairs of the leading coefficiant and constant term. </span>

Finito.
First, we can factor an x out of this.
We're left with x(x^2 - 16)
We can use the difference of squares theorem here to factor this further.

<h3><u>We're left with (x)(x + 4)(x - 4)</u></h3>
