Bài 2
a) \( x(3x + 2) = 5x(2x + 1) \)
b) \( x(x + 3) - (x + 3)(-2x + 4) = 0 \)
c) \( 2x(2x - 3) - 5(3 - 2x) = 0 \)
d) \( (3x - 1)(x + 2) = (x - 1)(2 + x) \)
e) \( (x + 2)(3 - 4x) = x^2 + 4x + 4 \)
f) \( x(2x - 7) - 6x + 21 = 0 \)
g) \( 3x - 15 = 2x(5 - x) \)
h) \( (2x + 1)(3x - 2) = (5x - 8)(2x + 1) \)
i) \( 5x(x - 3) = (x - 3)(1,5x - 1) \)
j) \( (2x^2 + 6)(4x - 3) = (x - 12)(2x^2 + 6) \)
k) \( x(2x - 9) = -3x(x - 5) \)
l) \( (x - 5)(5x + 3) = (3x - 8)(5 - x) \)
m) \( 2x(x - 1) = x^2 - 1 \)
n) \( (2 - 3x)(x + 11) = (3x - 2)(2 - 5x) \)
