1) \( x^2 - 9 = 0 \)
2) \( 2x(x - 3) + 3(3 - x) = 0 \)
3) \( 3x^2 - 4x - 7 = 0 \)
4) \( 2x(x + 3) - 2x^2 = 80 \)
5) \( 6x^2 - 10x = 0 \)
6) \( (x + 3)^2 - x(x + 3) = 8 \)
7) \( x^2 - 5x - 14 = 0 \)
8) \( (x - 1)^2 + λ(5 - x) = 8 \)
9) \( 3x(x - 3) + 4x - 12 = 0 \)
10) \( (x + 1)(x^2 - x + 1) - x^3 + 2x = 17 \)
11) \( 5(x - 4) + 2x - 8 = 0 \)
12) \( (x - 1)(x + 4) - 8x^3 + 4x = 19 \)
