Answer:
p(x) as a product of linear factors. 
Step-by-step explanation:
(x+3) is the factor of polynomial 
So, we can divide
by (x+3) to find other factors
The division is shown in figure attached.
The quotient is: x^2+4x-12
Now factoring the quotient to find linear factors

The factors are 
So, p(x) as a product of linear factors.
