1) \( (2x - 1)^2 - (4x^2 - 1) = 0 \)
2) \( (x + 2)^2 - x(x - 3) = 2 \)
3) \( (x - 5)^2 - x(x + 2) = 5 \)
4) \( (x - 1)^2 + x(4 - x) = 11 \)
5) \( (x - 3)(x + 3) = (x - 5)^2 \)
6) \( (2x + 1)^2 - 4x(x - 1) = 17 \)
7) \( (3x + 1)^2 - 9x(x - 2) = 25 \)
8) \( (3x - 2)(3x + 2) - 9(x - 1)x = 0 \)
9) \( (x + 2)^2 - (x - 2)(x + 2) = 0 \)
10) \( (x + 2)^2 - (x - 3)(x + 3) = -3 \)
11) \( (3x + 2)^2 - (3x - 5)(3x + 2) = 0 \)
12) \( (x + 3)^2 - (x + 2)(x - 2) = 4x + 17 \)
13) \( 3(x - 1)^2 + (x + 5)(2 - 3x) = -25 \)
14) \( (x + 3)^2 + (x - 2)^2 = 2x^2 \)
