University of Illinois: Quadratic Formula

Scholars first complete an individual assignment using a quadratic equation to model the movement of a bus around a corner. Learners then discuss their solutions with classmates and analyze the provided sample responses.

In this algebra worksheet, students sketch graphs of hyperbolas after solving equations to standard form and interpreting the center, vertices, foci, axis, asymptotes, and eccentricity from the equation. There are 58 questions.

Challenge: Sketch a graph of a quadratic function without making a table of values. High schoolers learn how different parameters affect the graph of a quadratic function. The problem video focuses on dilations of quadratic graphs.

Discusses how to find the area of a triangle using Heron's formula and provides interactive examples and problems you can solve.

This site from the University of St. Andrews provides an extensive history of quadratic, cubic, and quartic equations including various historical figures and their contributions to modern methods of solving quadratics.
