**1. Homework Statement**

Evaluate the indefinite integral.

int (6 x + 7)/(x^2 + 1) dx `

**3. The Attempt at a Solution**

A/(x + 1) + B/(x - 1)

6x + 7 = A(x - 1) + B(x + 1)

6x + 7 = (A + B)x + (-A + B)

A + B = 6

-A + B = 7

A + (7 + A) = 6

2A = -1.

A = -.5

B = 3.5

So the answer should be...

-.5ln(x + 1) + 3.5ln(x - 1) + C

Is this correct?
