1 / | | 1 | ------------ dx | 2 | x + 2*x - 3 | / 2
$$\int\limits_{2}^{1} \frac{1}{\left(x^{2} + 2 x\right) - 3}\, dx$$
Integral(1/(x^2 + 2*x - 3), (x, 2, 1))
The answer (Indefinite)

/ | | 1 log(3 + x) log(-1 + x) | ------------ dx = C - ---------- + ----------- | 2 4 4 | x + 2*x - 3 | /
$$\int \frac{1}{\left(x^{2} + 2 x\right) - 3}\, dx = C + \frac{\log{\left(x - 1 \right)}}{4} - \frac{\log{\left(x + 3 \right)}}{4}$$
