Bài 2: Tìm x:
a) 5 – (x – 6) = 4(2x – 3)
b) 3 – 4x + 24 + 6x = x + 27 + 3x
c) (x + 5)(x – 1) = 2x(x – 1)
d) 5(3x – 2) – 4(5 – 3x) = 1
e) (x + 3)(x – 5) + (x + 3)(3x – 4) = 0
f) 3(x – 1)(2x – 1) = 5(x + 8)(x – 1)
g) (x² – 5x + 7)² – (2x – 5)² = 0
h) x³ – 5x² + 6x = 0
i) x⁴ – 6x² + 5
j) x – x/x – 8
k) (x + 7)(3x – 1) = 49 – x²
l) 3x² – 7x + 4 = 0
m) 2x³ + 3x² – 32x = 48
