A tool designed to reverse the process of adding fractions by breaking down a rational function into simpler fractions. These simpler fractions, known as partial fractions, each have a denominator that is a factor of the original denominator. For example, a complex fraction like (3x + 5) / (x^2 + x – 2) can be separated into fractions with denominators of (x + 2) and (x – 1), making it easier to work with.
This type of utility is significant because it simplifies complex algebraic expressions, making them more manageable for integration, solving differential equations, and performing other mathematical operations. Historically, partial fraction decomposition was performed manually, a time-consuming process prone to errors. The automated nature of these utilities reduces errors and significantly accelerates problem-solving.
