Lesson Summary:
In this lesson, the ABC method for factoring trinomials of the form ax^2 + bx + c is explained and demonstrated. By taking the A, B, and C terms and using a specific technique, students can find the factors needed to factor the trinomial into two binomials. The lesson includes a step-by-step demonstration of the technique with a problem that has large numbers, but the method is applicable to any trinomial of this form.
Lesson Description:
The second part of factoring trinomials of the form ax^2 + bx + c.

Staff Review
This lesson is very similar to the previous one, but this video uses more complicated trinomials. They include both x and y in the terms. They are still factored by splitting up the middle term and factoring by grouping. A good example problem for learning factoring. -
