Chapter 1.1 Factorization of Quadratic Polynomials

Message to students:

In secondary two, students have learnt how to factorize quadratic polynomials by using identities. However, some quadratic polynomials cannot be factorized by this method. In this year, students would learn another method to factorize quadratic polynomials. This method is called the cross method. In the video, there is a demonstration on factorization of quadratic polynomials by cross method.
