Part 1:
You are familiar with the following types of factoring:

factoring out the Greatest Common Factor (GCF)
factoring by grouping
factoring trinomials of the form x^2 + bx + c and ax^2 + bx + c

As you know, you need to know the first two types of factoring listed above in order to be successful in factoring trinomials of the form ax^2 + bx + c. In your own words, explain how a trinomial of the form ax^2 + bx + c can be turned into a four term polynomial suitable for factoring by grouping. Use complete sentences and feel free to use a concrete example if needed.
