Rational Expressions
An algebraic fraction where both the numerator and the denominator are polynomials.
Simplification by Factorization
Splitting complex algebraic expressions into simpler factors to cancel out common terms in fractions.
Lowest Form of a Fraction
A fraction is in its lowest form when the numerator and denominator have no common factor other than 1.
Domain Restrictions
Identifying values of the variable for which the denominator becomes zero, making the fraction undefined.

Frequently Asked Questions
It refers to algebraic expressions that look complicated or like polynomials, but are actually fractions that can be simplified by factorizing them.
It refers to algebraic expressions that look complicated or like polynomials, but are actually fractions that can be simplified by factorizing them.
Can I cancel terms directly without factorizing?
No, you can only cancel common factors, not terms that are added or subtracted. You must factorize first.
Why is the denominator not allowed to be zero?
Division by zero is undefined in mathematics, so any value of the variable that makes the denominator zero must be excluded.
