Today, students studied writing quadratic equations and solving quadratic inequality with one variable. Writing equations requires at least three conditions and selects proper quadratic form to find the values that need to complete the equation, such as standard form and vertex form. In the quadratic inequality with one variable, factorization is still the major method. With the factor form, through positive and negative analysis of each binomial factor to find the values of the variable that satisfy the equality inequality. In next class, we will continue to solve quadratic inequality factorization through the roots and the case of no real roots.
