FACTORING COMMON MONOMIAL FACTOR

What is a Common Monomial Factor ?

A common monomial factor is a monomial that is a common factor to all of the terms of a polynomial expression.

Example of Monomial Expression :

8x5

Find the common monomial factor in monomial. 

8x5 = 2x2 . 4x3

8x= 8x . x4

8x= 2x . 2x . 2x . x2

It gives as a product of two or more monomials.

Example of Binomial Expression :

3x4 - 6x2

Find the common monomial factor in binomial.

3x4 - 6x2

Take out the greatest common factor,

= 3x2(x2 - 2)

Here the Common Monomial Factor is 3x2

Example of Trinomial Expression :

15x4 - 10x3 + 5x2

Find the common monomial factor in Trinomial.

15x- 10x+ 5x2

Take out the greatest common factor,

5x2(3x2 - 2x + 1)

Here the Common Monomial Factor is 5x2

Another example of Trinomial Expression :

36x4y2 - 18x3y5 - 9x3y2

Find the common monomial factor in Trinomial.

36x4y- 18x3y5 - 9x3y2

Take out the greatest common factor,

= 9x3y2(4x - 2y3 - 1)

Here the Common Monomial Factor is 9x3y2

Factor out the greatest common monomial factor.
