a) (3x + 2)(x 2 – 1) = (9x 2 – 4)(x + 1)
b)x(x + 3)(x – 3) – (x + 2)(x 2 – 2x + 4) = 0
c) 2x(x – 3) + 5(x – 3) = 0
d) (3x – 1)(x 2 + 2) = (3x – 1)(7x – 10)
e) (x + 2)(3 – 4x) = x 2 + 4x + 4
f) x(2x – 7) – 4x + 14 = 0
g) 3x – 15 = 2x(x – 5)
h) (2x + 1)(3x – 2) = (5x – 8)(2x + 1)
i) 0,5x(x – 3) = (x – 3)(1,5x – 1)
j) (2x 2 + 1)(4x – 3) = (x – 12)(2x 2 + 1)
k) x(2x – 9) = 3x(x – 5)
l) (x – 1)(5x + 3) = (3x – 8)(x – 1)
m) 2x(x – 1) = x 2 - 1
n) (2 – 3x)(x + 11) = (3x – 2)(2 – 5x)
lm hộ mk vs dc ko ah( mk sẽ vote 5* cho tất cả các bn lm dùm mk á)
cảm ơn ah
