The quotient of two polynomials is called a rational expression.
Simplify: The number 1 Simplify: The number 1
Rules for Adding and Subtracting Rational Expressions, Denominators Equal
Simplifying a Mixed Quotient First, treat the numerator and denominator separately, performing the indicated operation. Then, simplify the numerator and denominator.
