This video tutorial introduces the box method for multiplying binomials, a visual and organized approach that reduces errors. The instructor walks through examples, starting with simple binomials and progressing to more complex ones, demonstrating how to fill in the box and combine like terms. The video concludes with tips and a call to action to subscribe for more educational content.

What is the first step in using the box method for multiplying binomials?

• Combine like terms.

• Write the binomials around the box.

• Draw a box and divide it into four sections.

• Multiply the outer terms first.
