Data Representation and Quadratic Equations

This video tutorial covers a range of mathematical concepts, starting with the basics of finding the Greatest Common Factor (GCF) and moving on to more advanced topics like factoring polynomials and solving equations using the zero product property. It also explains the use of the discriminant in quadratic equations and concludes with data interpretation techniques using histograms and box plots.
