1. The problem statement, all variables and given/known data Can someone help me integrate (4x - 3) / (x^2 +1) ? 3. The attempt at a solution I'm doing my maths baccalaureate in 2 days and came across this question today! I don't know where to start i.e. which method to use: Integration by parts definitely does not work, nor does by substitution! Thank you!
