Math 9 Chapter 5 Factorization

1. To find out which numbers have interacted to form an original number and when these found out numbers are multiplied, added, divided or subtracted together, they make the original number is called factorization ie 4 can be 2x2 = 4 or 2+2 = 4 (writing 4 as 2x2 or 2+2 is factorization of 4)? When polynomial has been written as a product consisting only of prime factors then it is called? If a polynomial p(x) is divided by a linear divisor (x-a) then remainder is?
