Bài 8. Tìm x, biết:
a) (x+2)²-x(x+3) = 2
b) (x+2)(x-2)-(x + 1)² = 7
c) 6x² - (2x+1)(3x-2) = 1
d) (x+2)(x+3)(x-2)(x+1)=2
6(x-1)(x+1)-(2x-1)(3x+2)+3=0
f) x(3x+1)+(x-1)²-(2x+1)(2x-1)=0
g) (x+1)+(2-x)³-9(x − 3)(x+3) = 0
1) (x−1)²-(x+3)(x²-3x+9)+ 3x² = 25
k) (x+2)³ - (x + 1)(x²-x+1)-6(x-1)² = 23
m) (x+3)(x² −3x+9)-x(x − 2)(x+2)+11=0
n) x(x-3)-x+3=0
0) (x-1)(x+2)-2x-4-0
p) x²-3x² - 4x+12=0
q) 9(x-1)-x³ + x² = 0
r) x² - 2x²+x-2=0
t) (9-x²)(2x+1)=0
