Tìm nghiệm : a) (2x-3).(2x+3) B)(x-4).(x-1).(x-2) C)2x(3x-1)-3x(5+2x) D)(3x-2).(3x+2)-4.(x-1)
tìm x:|5(3x+1)|+|2(3x+1)|+|3x+1|=4
tìm x: 5(3x+1)|+|2(3x+1)|+|3x+1|=4
tìm x: 5(3x+1)|+|2(3x+1)|+|3x+1|=4
tìm x:|5(3x+1)|+|2(3x+1)|+|3x+1|=4
Tìm x,y:
f,/3x-1/+/3x-2/+/3x-3/+/3x-4/=4
Giải giúp tui!!
Tìm nghiệm:
3(x+2)-1/3(6-3x)
3x(x-5)-(x+3x)
Bài 2 Tìm x biết 1, (2x-2).(3x+1)-(3x-2).(2x-3)=5 2,(1-3x).(3x-5)-(2x-4)(2-3x)=x-6 3,(2x-1).(4x^2+2x+1)-(2x+1)(4x^2-2x+1)=5x+6 Giúp tớ với
Tìm x biết 3x+3x+1+3x+2=117
