.


I can instruct you immediately, without the reference to a video lesson.


<pre>
    1.  Under given info, simply divide the given polynomial of the degree 3 by the binomial (x+5), using long division, for example.



    2.  You will get the quadratic polynomial as a quotient.


        Find the roots of this quadratic polynomial.


        The associated linear binomials will be the factors of your given polynomial of the degree 3.
</pre>

That's all.
