Factorization of Polynomials Using Algebraic Identities
We know that the algebraic identities of second degree are
These identities can be used to factorise quadratic polynomials.
A polynomial is said to be cubic polynomial if its degree is three
The algebraic identities used in factorising a third degree polynomial are:
Cubic polynomials can be factorised using Factor theorem
Factor theorem:
is a polynomial and 
is a real number, if
, then 
is a factor of
