Bài 2. Giải các phương trình:
1) \( (3x - 2)^2 - 25 = 0 \)
2) \( x(3x + 5) - 6x - 10 = 0 \)
3) \( (x - 1)^2 + 4x - 4 = 0 \)
4) \( (x - 4)^2 = 5x - 20 \)
5) \( (2 - 3x)(x + 11) = (3x - 2)(2 - 5x) \)
6) \( (2x - 1)^2 + (2 - x)(2x - 1) = 0 \)
7) \( (9x^2 - 4)(x + 1) = (3x + 2)(x^2 - 1) \)
8) \( (x^2 - 4)(4x - 1) = (x - 2)(16x^2 - 1) \)
9) \( (x - 1)^2 + x^2 - 1 = (x - 1)(x + 3) \)
10) \( (2x - 3)^2 + 4x^2 - 9 = (2x - 3)(3x + 5) \)
11) \( (x - 3)^2 - 9 + x^2 = (x - 3)(x + 1) \)
12) \( (2x + 5)^2 - 25 + 4x^2 = (2x - 5)(5 - 9x) \)
