Everything You'll Have Covered

Quadratic equations arise in a rich diversity of mathematical and scientific phenomenon. Their ubiquity results from the quadratic equation's naturally occurring role in area models and in situations involving constant acceleration (or some analog thereof).

Quadratic equations involve polynomials, which are algebraic expressions comprising sums, products, whole number exponents, numbers, and variables. By way of algebraic manipulation, each polynomial can be written in the form

Writing a quadratic polynomial in standard form is a common algebraic task, and requires a thorough understanding of both combining like terms and the distributive law.

This Activity Object introduces quadratic equations and the aforementioned terminology, along with some real-life interpretations of the quadratic equation.
