First off, we'll convert the mixed fractions to "improper", and proceed,
Separating the integral, we get the integral of 1/x minus the integral of 4/(x^2+1). From memory, I know that the integral of 1/x is ln(x). Next, I can separate the 4 from 4/(x^2+1), and I know from memory that the integral of 1/(x^2+1) is arctan(x). Therefore, your answer is ln(x)+C-4arctan(x)+C=ln(x)+4arctanx+C (Since C simply represents any number, we don't need to make it 2C. In addition, the C after 4arctan(x) and ln(x) could be different, so C-C would be some constant C too in this case)

10 equals 40
