Factoring Trinomials
In this lesson on factoring trinomials, the instructor shows several methods for factoring trinomials, including using algebra tiles, the cross method, and the Punnet square method. They also emphasize the importance of finding two numbers that multiply to the top number and add to the middle number when factoring trinomials. The instructor also provides shortcuts for factoring trinomials with a coefficient of 1 and shows how to determine if a trinomial can be factored using integers. Overall, this lesson provides a comprehensive overview of factoring trinomials and offers various methods for approaching the topic.
A straight-forward way to factor any trinomial. Rewriting a trinomial and factoring it by grouping. Also, factoring a trinomial using a Punnet Square.

Staff Review
This is one of the most despised lessons in Algebra. If you have a good foundation in factoring by grouping and you a fool-proof method of factoring that works every time (without ever using the guess and check method), give this lesson a try. Great factoring resources make this lesson a well-rounded, very complete lesson in and of itself. If you ever struggle with factoring a trinomial, this is the lesson for you. -

How is this suppose to work when your taking a test! Impossible! No time nor materials during a test to do this. Im so lost! This is not a good example in helping you for a test.
