For

x \in (1; 2)

choose the correct form of the equation

| 2 x^{2} - 5 x - 7 | = | x^{2} - 3 x + 1 |

that does not contain an absolute value.

- 2 x^{2} + 5 x + 7 = - x^{2} + 3 x - 1

2 x^{2} - 5 x - 7 = - x^{2} + 3 x - 1

2 x^{2} + 5 x + 7 = x^{2} - 3 x + 1

- 2 x^{2} + 5 x + 7 = x^{2} - 3 x + 1
