three terms.
Like this guy:
Right now, we're really interested
in a certain type of trinomial...
Remember FOIL?
We can multiply

and get |

Hey -- that's our trinomial from
above.
Basically, we'll be figuring out
how to "undo" guys like
|
into
their factors: |
|
You'll mostly be needing to know
how to do this to solve equations like
(which we'll do
later)
