Students discover how to factor a quadratic function using the Box Method.
The document begins with a quadratic expression with a = 12,
b = –13, and c = –4. Each successive page will instruct students how to create a "box" with organized terms that will lead to the factors of the polynomial.
A spreadsheet helps the student to find a pair of factors that add to the linear term. Even negative and positive numbers may be tested to find the correct pair. In this case, 3 and –16 works, while no other pair has a sum of –13x.
The values are stored so that the next few steps can be completed by the student.
