Solving Quadratic Equations 3: The Quadratic Formula
In this voicethread, students are introduced to a new rule: the quadratic formula. This easy to apply rule for equations given in the general form can be implemented to find the zeroes of a quadratic function, particularly in cases where easy factoring is not possible or when the factors are not integers.
Learning Goals:
To be able to solve an equation of the second degree in one variable using the quadratic formula
