Adding and Subtracting Rational Expressions: Tips and Tricks for Simplifying Algebraic Fractions - legacy
A rational expression is the ratio of two polynomials, typically represented as a fraction. Rational expressions can be simplified by factoring or canceling common factors.
How Do I Handle Zero Denominators?
Adding and subtracting rational expressions involves combining or comparing fractions with different denominators. The process typically begins by finding a common denominator, which is the least common multiple (LCM) of the two denominators. Once the denominators are equal, the numerators can be added or subtracted. For instance, the expression (2x + 3) / (x + 1) - (x - 2) / (x + 1) can be simplified by finding a common denominator and combining the numerators.
