86. Partial fractions from an integral A computer algebra system was used to obtain the following result. 2x4 + 14x3 + 14x2 + 51x + 19 dx 2 5 + 24 + 323 + 3ac2 - 4x - 4 3 = 5 In (x - 1) - 3 In (x +1) - - tan -1 N/ 8 + C x+1 2 Use this fact to find the partial fraction decomposition of the integrand on the left side of the equation
