Quadratic Equations

Software for teaching and learning of quadratic equations. It covers solutions by factorisation, "completing the square" and formula. Each method is clearly explained, with simple sums for practice. Can generate hundreds of sums (up to 200 sums per session) for drills. The type of sums is...

Prime sprial plotting software for square (Ulam) and related polygon prime number spirals. Allows multiple prime generating quadratic equations to be displayed simultaneously. Plot data and image files can be saved to disk for further analysis. Demo version is limited to prime spirals based on...

Quadratic-O-Matic is about the simplest program imaginable to set up and to use. You simply call the program up in your web browser, type in the numbers to get your quadratic equation, and click "Solve that puppy."You will then be given the roots of the equation.If "b2 - 4ac" is negative, you'll...
