Express the integrand as a sum of partial fractions and evaluate the integrals. x + 2 -dx x- + 3x - 4 . . 1 Express the integrand as a sum of partial fractions. Select the correct choice below, and, if necessary, fill in any answer boxes to complete your choice. (Use integers or fractions for any numbers in the expression.) O A. x + 2 dx = dx x2 + 3x - 4 x+2 x-2 O B. x + 2 -dx = + dx x- + 3x - 4 X + 4 x - 1 OC. x + 2 -dx = dx x2 + 3x - 4 x2 + 4 x2- 1
