Factoring a trinomial by factoring out a variable first then solving

The video tutorial introduces the concept of factoring, starting with simple numbers and moving to polynomials. It explains the process of breaking down numbers and polynomials into their factors, using examples like 6 and 12. The tutorial then transitions to polynomial factoring, emphasizing the importance of finding the greatest common factor (GCF) and using techniques like the diamond method. The lesson concludes with verifying the factors and a brief mention of solving equations, which will be covered in the next chapter.

How can you determine if the factors of a polynomial are correct?

What is the significance of setting the factors equal to zero?
