1, warm-up knowledge: Before watching the video, review the basic knowledge related to factorization quickly, so that you can keep up with the rhythm of the video faster.

Step-by-step learning: Don't try to watch the whole video at once. Divide the video into several small parts, and briefly review after each part to make sure you understand each step.

3. Stop thinking: When you don't understand something in the video, don't hesitate to stop the video immediately. Give yourself some time to think, or go back to the textbook to find relevant knowledge points, and then continue to play.

4. Note-taking: Prepare a notebook to record important ideas, examples and problem-solving skills in the video. This will help you to deepen your memory and find the key information quickly in the subsequent review.

5. Do exercises: Just watching videos is not enough. You need to consolidate what you have learned through a lot of practice. After watching each video clip, try to do some exercises related to the video content.

6. Proof and discussion: Don't be shy when you encounter problems that you can't solve, and discuss them with teachers or classmates in time. Through discussion, we can find problems faster and deepen our understanding of knowledge points.

7. Watch it again and again: If you have never understood a certain knowledge point, you may wish to watch this part of the video again and again. Repetition may help you find a breakthrough in understanding.

8, combined with other resources: video tutorial is just one of many learning resources. You can also refer to textbooks, teaching AIDS, online forums, etc. Understand the concept and method of factorization from multiple angles.

Matters needing attention in mathematical factorization:

1, master the definition and basic methods of factorization, including common factor extraction method, formula method, grouping decomposition method, etc.

2. When factorizing, we should first choose the appropriate factorization method. For example, polynomials with three or more terms need grouping factorization.

3. Decomposition should follow the steps of extracting common factors first, and then using formula method or group decomposition method.

4. The result of factorization needs the product of several algebraic expressions, and the first sign of each factor is positive.

5. Pay attention to check whether there are common factors in the final result of factorization, or whether further adjustment is needed.

6. In factorization, we should use all kinds of methods flexibly, especially formula method, memorize all kinds of formulas and use them skillfully.

7. After factorization, the order of the whole formula should be adjusted or simplified appropriately to make the whole formula cleaner and more readable.

8. Note that factorization and multiplication are two opposite transformations, so don't confuse them.
