What methods do you need to master in factorization of eighth grade mathematics (People's Education Edition)?
Hello, factorization is divided into the following parts; 1. common factor method 2. The formula method needs to be skillfully used. Cross multiplication is just a backup. If the first two methods fail, you can try. Cross multiplication is as follows. X2+(q+p)x+qp If all three methods fail, there is a final population decomposition method to complete factorization. Generally, a complete square formula will appear at this time.

The answer is not easy to adopt.
