(4) (a) What is the correct form of the partial fraction decomposition for the following integral? 2 2 + 1 (2 - 1) 3(x2 + 10x + 49) da O A. A Be + C (a - 1)3 dx x2 + 10x + 49 B. / A B C (x - 1)3 dx x - 10 x - 49 O C. There is no partial fraction decomposition yet because there is cancellation. D. 7 - 1 Ba +C Dx + E Fx +G (a - 1)2 (2 - 1)3 . + dx x2 + 10x + 49 E. There is no partial fraction decomposition yet because long division must be done first. OF. 2 - 1 B C Dx + E (2 - 1)2 (2 - 1)3 dx a2 + 10x + 49 A B C OG. (x - 1 ) 3 Da + E dx x - 10 (x - 10)2 a2 + 1 OH. There is no partial fraction decomposition because the denominator does not factor. (b) Split into partial fractions: 30 25 - 2-2
