Thank you for the opportunity to help you with your question!

---------------------------------------------------------------------------------------------------------------

x = -3 is a zero of the polynomial

So x + 3 is a factor.


Divide f(x) by (x+3) to find the other factors.


So


Now factorize   since we need linear factors. We can use the quadratic formula to do that.

a = 1, b = 6, c = 6

The quadratic formula is
