An Algorithm for Partial-Fraction Expansion
Joseph W. Rogers, Margaret Anne Rogers · Mathematics Teacher Learning and Teaching PK-12 · 1972
We Usually expand a rational function by first reducing it to the sum of a polynomial and a proper fraction that is the quotient of two polynomials in which the degree of the numerator is less than the degree of the denominator. We expand the fraction by writing it as a sum of partial fractions with undetermined numerator coefficients.
