Equations: Linear & Quadratic

There are many excellent online resources for learning about and solving equations.
Note that WolframAlpha is excellent for checking solutions to equations.

Solve equations with Wolfram Alpha

Absolute value equations

Note that you can change the equations inside the above widgets.
Alternatively – just type your equation into WolframAlpha.
(Note that step by step solutions are for pro subscribers but you can get answers to as many equations as you want, so WolframAlpha is great for checking work).


Mathisfun has this very clear and easy to use interactive illustrating the solution of linear equations.

Also from Mathisfun we have a Quadratic Equation Solversimply enter the coefficients (a, b and c) and the solutions and a graph will be returned.


Try this calculator from Math Warehouse which shows the working very clearly using the formula.
