BLOSSOMS - The Quadratic Equation: It's Hip to Be Squared
By: Gilbert Strang
Summary: This lesson aims to help students with quadratic functions y = ax2 + bx + c. This is the next step after linear functions bx + c. The lesson begins with three quadratics and their graphs (three parabolas): y = x2 - 2x + (0 or 1 or 2). The prerequisite or co-requisite for this lesson is some working experience with algebra, like factoring x2 -2x into x(x-2).
