Simplifying Algebraic Fractions in GCSE Mathematics
This page provides a comprehensive overview of simplifying algebraic fractions, a fundamental skill for GCSE mathematics students. The worksheet presents several examples of algebraic fractions, demonstrating the step-by-step process of simplification.
Highlight: Simplifying algebraic fractions often requires factorization as a crucial step.
The first example shows the simplification of (x² + 2x) / (x² - 3x). This fraction is simplified by factoring out the common term x from both the numerator and denominator, resulting in a simpler expression.
Example: (x² + 2x) / (x² - 3x) simplifies to (x(x + 2)) / (x(x - 3)), which further reduces to (x + 2) / (x - 3) after canceling the common factor x.
The second example demonstrates the simplification of a more complex fraction: (2y² + y) / (2y - 3). This problem requires careful factorization of the numerator to identify common terms that can be canceled with the denominator.
Vocabulary: Factorization is the process of breaking down an algebraic expression into the product of its factors.
The third example showcases a more intricate simplification process involving the fraction (2x² - 3x - 2) / (x² - 4). This problem emphasizes the importance of thorough factorization in both the numerator and denominator before attempting to cancel common terms.
Definition: An algebraic fraction is a fraction where the numerator, denominator, or both contain algebraic expressions.
The worksheet also includes a step-by-step breakdown of factorizing the expression 2x² - 4x + x - 2. This example illustrates how to group terms and identify common factors to simplify complex expressions.
Example: 2x² - 4x + x - 2 can be factored as 2x(x - 2) + 1(x - 2), which further simplifies to (2x + 1)(x - 2).
Finally, the page emphasizes that factorization is usually necessary to simplify algebraic fractions effectively. This reinforces the importance of strong factorization skills in handling more complex algebraic problems.
