BS Editor: Factorisation of Trinomials, Factorisation by
Formulas of Perfect Squares and Difference of Two Squares
Tutorial
Teaches algebraic factors - the factorisation of algebraic expressions, with emphasis on trinomials such as x2 + 5x + 6, because it is important to master this skill. The procedure in algebraic factorization is explained in detail to ensure that students understand how it works. Many practice sessions are provided in the process to ensure that the student understands each step.
Practice
AlgeFactors is capable of generating hundreds of sums for drills to ensure that the student masters the skills. It also includes sums involving perfect squares, such as 4x2 - 12x + 9 and difference of two squares, such as 9x2 - 25. These sums can be solved by using formulas.
The student may also key in his own sums and let the guide help him do them.
Worked Examples
Almost 50 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 factorisation 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.
AlgeFactors is able to accept nearly all correct alternative
Answers.
In this example, the following answers will all be accepted as correct: Factorise
2x2 + 6x + 4
2(x + 1)(x + 2) or 2(x + 2)(x + 1)
2(1 + x)(2 + x) or 2(2 + x)(1 + x)
2(1 + x)(x + 2) or 2(x + 2)(1 + x)
2(x + 1)(2 + x) or 2(2 + x)(x + 1)
