Mathematics is for everyone!

Purpose: to help high school students overcome challenges in Quadratics

Algebra 101- Solving Quadratic Equations
Self-paced Tutorial

Quadratic equations are a fundamental topic in high school mathematics around the world. Moreover, like linear equations,  quadratic equations are essential representations used in other disciplines, such as physics, engineering, and design, due to their usefulness in solving real-world problems and mathematical modelling. 

Methods for Solving Quadratic Equations

Solving Quadratic Equations:  This high school level tutorial is developed as a self-directed course of study. In this first tutorial, only two methods of solving quadratic equations will be covered. Though students are expected to have the required pre-requisite skills, a page has been included with resources reviewing the necessary previous knowledge

Learning objectives:  

• use factoring to solve quadratic equations

• apply the quadratic formula to solve quadratic equations. 

Tutorial Content

The following resources are available to meet the objectives:

• video resources- modelling the steps for solving quadratic equations using factoring and the quadratic formula
• ebook- to provide supplemental information and further examples
• online calculator- to verify solutions to practice questions

ebook Beginning_and_Intermediate_Algebra.pdf
