Factoring and Fractions
By M Bourne
Many mathematics formulas involve factoring. It makes your (mathematical) life a lot easier if you are confident when factoring complex expressions.
Even though we use decimals more than we use fractions in everyday life, an understanding of fractions is still important in mathematics, especially in algebra.

We start with a reminder on how to expand expressions like (x + y)2 in the Special Products section.
Then we will learn how to:
- Factor expressions like a2 − b2 in Difference of Squares, followed by...
- Factor Trinomials (eg 3a2 + 2ab − b2) then
- Factor Cubes like `a^3 - b^3`.
The final part of this chapter is about algebraic fractions.
- We first recall what an Equivalent Fraction means and learn how to factor fractions.
- Then we see how to Multiply and Divide Algebraic fractions, followed by...
- Adding and Subtracting Algebraic Fractions
- Finally, we see some examples and applications of Equations involving Fractions.
The chapter begins with 1. Special Products »
