Q1.1 Multiple Choice 1 Point x2 - 12x - 17 To evaluate (ac - 1) 2(202 + 1) dac using the method of partial fractions, which form of the partial fraction decomposition should be used? O x2 - 12x - 17 A B Ca+ D A. (a - 1) 2(ac2 + 1) x- 1 (ac - 1)2 x2 + 1 O x2 - 12x - 17 A B C B. (ac - 1) 2(2 2 + 1) ex - 1 (a - 1)2 2 + 1 O 2 - 12x - 17 A C. (ac - 1) 2 (ac2 + 1 ) = (a + 10x + 139) + x2 - 12x - 17 O x2 - 12x - 17 A Ba + C D. ( ac - 1)2 (2 2 + 1) (ac - 1)2 + x2 + 1 O x2 - 12x - 17 A Bx C E. + + (ac - 1) 2 (ac2 + 1) x - ex - 1 x2 + 1 O F. None of the above is correctQ2.1 1 Point 1 A B The rational function f (a) = can be written in the form (ac + 1) (2 - 4) x+1 ex - 4 What are the values of A and B? O A. A = =, B = O B. A = - , B = - O/ K O C. A = -=, B = OH OH OD. A = =, B = - O E. None of the aboveQ2.2 General form 1 Point 1 The rational function f (a ) = ( ac + a ) (20 + 6) where a, b be two chosen constants (real A B numbers), can be written in the form x - a x + 6 (In the previous question, a = 1, b = -4.) What are the values of A and B? O A. A = 7 6, B =- a - b O B. A = h, B = a -b O C. A = - -, B = - a -b OD. A = - -! a b , B = a - b O E. None of the above
