Title

Finding the number of intersection points of two quadratics using the discriminant (MathsCasts)

Creator

Vida Weiss

Description

For a quadratic equation of the form ax^2+bx+c=0, the discriminant function b^2-4ac is introduced, as a way of determining how many roots this equation has. This is then applied to problems of determining how many points of intersection the curves representing quadratic functions have.
