We have been given a polynomial and we are asked to factor our polynomial by double grouping.

First of all we will group terms with common factors. We can see that
and 2x have a common factor x. Common factor of -3x and -6 is -3.


Now we will factor out Greatest Common Factor from each group.
After factoring out GCF from each group we got (x+2) as our common binomial. Now we will write our polynomial as a product of two binomials as:
Therefore, our polynomial as a product of two binomials will be
.
We can write it down as a fraction:

and we can simplify this fraction:
=

=

=

or we can write it as a decimal:
0.1282...
