Algebraic Fraction

An algebraic fraction is a fraction where the numerator, the denominator, or both contain algebraic expressions (terms with variables). They follow the same rules as regular fractions but involve variables like x, y, a, or b

Key Points on Algebraic Fraction: 

1. The numerator and/or denominator include variables. 

2. The denominator cannot be zero (e.g., in 1x, x0). 

3. They can often be simplified by factoring or canceling common terms. 

Examples of Algebraic Fration: 

1. Simple Algebraic Fraction: 

   2x+53 

   Explanation: The numerator 2x+5 is an algebraic expression, while the denominator is a number. 

2. Fraction with Variable in Denominator: 

   7y2 

   Explanation: The denominator y2 is an algebraic expression. Here, y2 (since division by zero is undefined). 

3. Simplifiable Algebraic Fraction: 

   x29x+3 

   Simplification: Factor the numerator: 

   (x3)(x+3)(x+3). Cancel x+3 (if x3): 

   Simplified form: x3
