Today, I started the new chapter, quadratic equations, basic nonlinear, but very important, expressions and equations. I introduced the basic concepts of quadratic expression and equations, and the methods to solve the quadratic equations with coefficient of quadratic term being 1. The first method introduced is factoring quadratic expression, the process of inverse of the distributive to the product of two binomials. Through the factor form of quadratic equation, you can find the solutions of the quadratic equation easily.

Here is the homework reflecting the contents in today’s class,
