Algebraic Manipulation
Akopọ
Algebraic manipulation is the backbone of the Edexcel IGCSE Mathematics course. It covers the skills you need to rewrite, simplify and rearrange algebraic expressions: substituting values into formulas, collecting like terms, expanding brackets, and factorising. These techniques appear in almost every topic from equations and inequalities to coordinate geometry and calculus.
At Foundation tier you will master substitution, single-bracket expansion, common-factor extraction and double-bracket expansion, alongside factorising quadratics of the form \(x^2 + bx + c\). Higher tier extends to triple-bracket expansion, factorising \(ax^2 + bx + c\), manipulating algebraic fractions, completing the square, and constructing algebraic proofs.
Awọn Afojusun
- Evaluate expressions by substituting numerical values for letters
- Collect like terms
- Multiply a single term over a bracket
- Take out common factors
- Expand the product of two simple linear expressions
- Understand the concept of a quadratic expression and be able to factorise such expressions (limited to x^2 + bx + c at Foundation)
- [Higher] Expand the product of two or more linear expressions
- [Higher] Factorise quadratic expressions including those of the form ax^2 + bx + c
- [Higher] Manipulate algebraic fractions where the numerator and/or the denominator can be numeric, linear or quadratic
- [Higher] Complete the square for a given quadratic expression
- [Higher] Use algebra to support and construct proofs
