Step-by-step explanation:
We are given zeroes and we need to find a cubic function with these zeroes
zeroes given are :![\sqrt{6} , - \sqrt{6} , -3](/tpl/images/0186/3713/09088.png)
Since these are zeroes so these can be written as:
⇒![(x-\sqrt{6} )(x+\sqrt{6} )(x+3) = 0](/tpl/images/0186/3713/b2bbb.png)
⇒![(x^{2} +\sqrt{6} x- \sqrt{6} x -6)(x+3)](/tpl/images/0186/3713/db0ff.png)
⇒![(x^{2} -6)(x+3)](/tpl/images/0186/3713/03a8b.png)
⇒![x^{3} +3x^{2} -6x-18](/tpl/images/0186/3713/ed425.png)
Thus the required cubic function is![x^{3} +3x^{2} -6x-18](/tpl/images/0186/3713/ed425.png)
