The first thing you should do is to determine all the zeros, and you will have 7, -11, 2 + 6i, 2 - 6i.
After that you have to subtract and (x) from every each zero that you have above, which means
[tex]7-x,
-11-x,
2 + 6i-x,
2 - 6i-x
[/tex]
And the last step is to multiply them together, and that's all you need!
[tex](7-x)(-11-x)(2 + 6i-x)(2 - 6i-x)[/tex]
I am pretty sure that everything hase become clear! Regards.
