Determining Rational X Intercepts of Quadratic Functions through Factoring

This video tutorial explains how to determine the number of rational X intercepts in the graph of a quadratic function by examining the factorization method used. It covers the concept of rational and irrational numbers, the zero product property, and different types of quadratic functions, including factorable functions, monomial factorization, perfect square trinomials, and trinomials with different factors. The tutorial emphasizes that factorable functions have rational X intercepts, while non-factorable ones may have irrational intercepts. It also highlights the significance of the graph's symmetry and the role of the Y-axis.
