Factoring using the difference of two squares

The video tutorial covers the process of factoring expressions, focusing on identifying and working with square terms. The instructor explains that while some expressions can be factored by recognizing that A equals 1, others require identifying square terms. The tutorial demonstrates how to factor expressions with squared terms using the formula (A - B)(A + B) and verifies the solution by checking the middle terms. The session concludes with a final answer verification.

What should you do if the coefficient A is not equal to 1 in a factoring problem?

• Divide it by the variable term

• Multiply it by the constant term

• Factor it out first

• Ignore it and proceed with factoring
