Easy way

A%2Fx + B%2F%28x%2B1%29 = %28A%2A%28x%2B1%29+%2B+Bx%29%2F%28x%2A%28x%2B1%29%29 = %28%28A%2BB%29x+%2B+A%29%2F%28x%5E2%2Bx%29.


Since the right side is equal to  %282x%2B1%29%2F%28%28x%5E2%29%2Bx%29, according to the condition, it implies for the coefficients

B = 1  and  A+B = 2.


Hence, B = 1 and A = 1.


Answer.  A = 1  and  B = 1.
