Web21 May 2024 · First you have to factor the denominators into linear or quadratic factors. In this case 1 - x^3 = (1 - x)* (1 + x + x^2) 1 + x^3 = (1 + x)* (1 - x + x^2) Those factors will be the denominators of the partial fractions. The numerators will be of lower degree, with unknown constant coefficients, so the numerator of a fraction with a degree-1 ...
