Fisch Video: Factoring Polynomials by Grouping
Sometimes, we can factor a polynomial containing four or more terms by factoring common monomials from groups of terms. This method is called factor by grouping.
The next example illustrates how this process works.
We factor 3x from the first two terms and factor 4 from the last two terms:
Now the polynomial is factored completely.
Factor by grouping.
