If x+3 is one factor of x^3 +27 what is the other factor

For this case we have the following third degree polynomial:
 
 By completely factoring the polynomial we have:
 
 We will verify that the factorization is correct.
 For this, we make distributive property:
 
 We add similar terms:
 
 Therefore, the factorization is correct.
 So, the other factor is:
 
 
 the other factor is:
