6. Partial Fraction Decomposition a. As a partial fraction decomposition, we set -2+7 x(x+7) (x-1)2(x+1) equal to # + B + D (2-1)2 + *+1 E Find A - D. 2 b. As a partial fraction decomposition, we set 3x2-8x+1 (x-3)(x+1)(x-2) equal to C. Find A + 2B - C. c. Suppose the partial fraction decomposition of 5x -923+912+4r+8 (x-1)(x-2)(x2) (2+1) has the form A x+1 + 7-2 + -1 + + 5. Find the value of B + E
