In this way, a system of linear equations is obtained which always has a unique solution. Since two polynomials are equal if and only if their corresponding coefficients are equal, we can equate the coefficients of like terms. We then obtain an equation of polynomials whose left-hand side is simply p( x) and whose right-hand side has coefficients which are linear expressions of the constants A ir, B ir, and C ir. The most straightforward method is to multiply through by the common denominator q( x). There are a number of ways the constants can be found. Here, P( x) is a (possibly zero) polynomial, and the A ir, B ir, and C ir are real constants. In symbols, the partial fraction decomposition of a rational fraction of the form f ( x ) g ( x ), ![]() The concept was discovered independently in 1702 by both Johann Bernoulli and Gottfried Leibniz. The importance of the partial fraction decomposition lies in the fact that it provides algorithms for various computations with rational functions, including the explicit computation of antiderivatives, Taylor series expansions, inverse Z-transforms, and inverse Laplace transforms. In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction (that is, a fraction such that the numerator and the denominator are both polynomials) is an operation that consists of expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions with a simpler denominator.
