1, the definition of factorization: transforming a polynomial into the product of several algebraic expressions in a range of values is called factorization of the polynomial, also known as factorization of the polynomial.

2. Factorization Factorization: Factorization is one of the most important identical deformations in middle school mathematics. It is widely used in elementary mathematics, drawing roots in mathematics and solving quadratic equations with one variable. It is a powerful tool to solve many mathematical problems.

3. Significance of factorization: The factorization method is flexible and skillful. Learning these methods and skills is not only necessary to master the content of factorization, but also plays a very unique role in cultivating problem-solving skills and developing thinking ability. Learning it can not only review the four operations of algebraic expressions, but also lay a good foundation for learning scores; Learning it well can not only cultivate students' ability of observation, thinking development and calculation, but also improve students' ability of comprehensive analysis and problem solving.
