Factoring and Prime Factorization Concepts

The video tutorial explains how to factor a trinomial by identifying and using the greatest common factor (GCF). It begins with determining the prime factorization of each term in the trinomial, then identifies the GCF by finding common factors. The tutorial demonstrates factoring the trinomial by factoring out the GCF and verifies the result by multiplying the factors to ensure the original trinomial is obtained.

What is the first step in factoring a trinomial by its greatest common factor?

• Divide each term by the smallest number

• Add all the terms together

• Find the prime factorization of each term

• Determine the coefficients

• 3 x 5 x 6

• 2 x 5 x 6

• 3 x 3 x 5
