Tutorial
Teaches the solution of quadratic equations by factorisation, by completing the squares and by formula. Special cases of equations involving perfect squares and difference of two squares, using special
Formulas are also included. It also shows how the formula is derived by using the completing the squares method. Emphasis is given to solution by factors which is important at this level.
Practice
QuadEquations is capable of generating thousands of quadratic equations for drills to ensure that the student masters the skills in solving quadratic equations. The student can select to be provided with equations which can be solved by a method or level of difficulty he likes. Three levels of difficulty are available: easy, average and challenging.
The student may also key in his own equations and let the guide help him solve them.
Worked Examples
Thirty worked examples provide help for students who have difficulty in solving the equations.
Reports
You can print out a report at the end of each practice session. The report shows each sum with its correct answer and the student's answer
Marked. It also includes the percentage score, the average
Time taken to do each sum and other details.
Special Features
A step by step interactive guide is provided to help the student solve the equations if he has difficulties. If more than one method is available, the user is allowed to make a choice. The guide does not solve the equation for the student but guides him along, providing feedback on his working after each step. This helps the student to learn the method.
A student can key in his own equation and let the guide help him solve it. This feature can help the student do his homework.
It allows two players to compete with each other on one computer, reducing the number of computers required for a class by half. Each player can do the sums at his own pace.
It prints two separate detailed reports, each showing the sums
