Quadratics are polynomials of degree 2. These polynomials have some interesting properties. There are quadratics with special structures such as perfect squares and differences of squares. Many quadratics can be factors and we will be looking at how to factor different quadratics. Here we are introducing you to quadratics and how to factor “nice” quadratics.
