Factorisation

**Factorization**is the decomposition of an algebraic expression into product of factors. Factors of an algebraic term can be numbers or algebraic variables or algebraic expressions.

For example, the factors of 2*a*^{2}*b* are 2, *a*, *a*, *b*, since 2*a*^{2}*b* = 2 × *a* × *a *× *b*

The factors, 2, *a*, *a*, *b*, are said to be irreducible factors of 2*a*^{2}*b* since they cannot be expressed further as a product of factors.

Also, 2*a*^{2}*b* = 1 × 2 × *a* × *a* × *b*

Therefore, 1 is also a factor of 2*a…*
