Tutorial

Teaches algebraic expansion - the expansion of algebraic expressions such as 3(x + 3), (2x - 5)(3x + 7), (x + 5)², etc. Emphasis is on doing the expansion in a systematic way, to avoid careless mistakes. Simple exercises at the end of the sessions allow students to practice what they have learnt immediately.

Practice

AlgeXpansion is capable of generating hundreds of sums for drills to ensure that the student masters the skills. It includes sums involving perfect squares, such as (2x - 3)² and difference of two squares, such as (2x + 5)(2x - 5). These sums can be solved by using formulas. More challenging sums such as (x + 5)(x² - 5x + 6) are also included.

The student may also key in his own sums and let the guide help him solve them.

Worked Examples

Almost 40 worked examples provide help for students who have difficulty in doing the sums.

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 do the expansion if he has difficulties. The guide does not do the sum for the student but guides him along, providing feedback on his working.

A student can key in his own sums and let the guide help him do it. This feature can help the student do his homework. Any pair of factors of 2 terms by 2 terms like (2x² - 3x)(4x + 5) or 2 terms by 3 terms like (3x² - 2x)(3x³ - 2x² + x). Any other letter may be used as a variable instead of x. (Coefficients of x are limited to between -30 and 30. Indices must be single digit.)

Allows two players to compete with each other on one computer with synchronised start for both players. A separate report is generated for each of the players.
