Factoring a polynomial using the difference of two cubes

The video tutorial explains the process of factoring expressions in the format a^3 - b^3. It begins by introducing the concept of cubed numbers and the importance of recognizing them. The teacher then guides through the factoring process, emphasizing the identification of the greatest common factor (GCF). The lesson continues with calculating cube roots to determine the values of A and B, which are then used in the factoring formula. The tutorial concludes with deriving the final factored form and addressing any questions.
