I2x+1/3I+3/4=0
|2x+1/3|=-3/4
TH1:
2x+1/3=-3/4
2x=-3/4-1/3
2x=-13/12
x=-13/12:2
x=-13/24
TH2:
2x+1/3=3/4
2x=3/4-2/3
2x=5/12
x=5/12:2
x=5/24
vậy x=-13/24;5/24
tìm x biết
b) 3x - x^3=0
c) (x-1).(x-3)=0
d) Ix+1I + Ix+2I+I2x+3I=2016x
tìm x
a,I2x-1I=x-2
b,I2x+1I=3x
c,I2x+1I=4
d,Ix-3I=1/2
e,Ix+1I+Ix-2I=0
f,I2x-1I+Ix+2I=0
tìm x Ix-1/2I + 2 = 3/4 - 4
b) 2- I2x +3I * 3 = -4
TÌM X biết I2x-3I=7/3
tìm giá trị x thỏa mãn I2x+3I + I2x-1I = 8/3(x+1)^2+2
Tìm x biết
a,I5(2x+3)I+I2(2x+3)I+I2x+3I=16
b,Ix+I6x-2II=x^2+4
Tìm x biết I2x+3I=x+2
tìm x
I2x-3I-I3x-2I=0
Tìm x biết: Ix-3I = I2x+1I
