2 . ( x³ -1)-2x²(x+2x⁴) +(4x⁵+4)x=6. 3. (X²-4x+16)(x+4)-x(x+1)(x+2)+3x²= 0 4 . ( 8x +2 ) (1-3x) + ( 6x-1)(4x-10) =-50 Đề bài là tìm x nha mn Nhanh giúp mik vs
TÌM X: 3x(4x + 1) - 6 (2x-3) - 6 (x+1) = 0
ai giúp mình câu này đc ko mình cần gấp (ko chắc)
\(a,4x-8/2x^2+1=0 b,x2-x-6/x-3=0 c,x+5/3x-6-1/2=2x-3/2x-4 d,12/1-9x^2=1-3x/1+3x-1+3x/1-3x\)
Đề: Tìm x
a)2x.(3x+5)-x.(6x-1)=33 k)5(x+3)-2x(x+3)=0
b)x(3x-1)+12x-4=0 i)5x(x-2)-(2-x)=0
c)5x(2x+1)-12x-6=0 m)x(x-1)-2(1-x)=0
d)x3-5x2+4x-20=0
e)2x3-5x2+2x-5=0
g)(x-2)3-x(x+1).(x-1)+62=5
Tìm x, biết:
a) 4x(x + 1) + (3 – 2x)(3 + 2x) = 15
b) 3x(x – 20012) – x + 20012 = 0
bài 3:
a) 27-x3/5x+5 : 2x-6/3x+3
b) (4x2-16) : 3x+6/7x-2
c) 3x3+3/x-1 : (x2-x+1)
d) 4x+6y/x-1 : 4x2+12xy+9y2/1-x3
Tìm x, biết:
a) x3 - 5x2 + 8x - 4= 0
b) 2x3 - x2 + 3x + 6= 0
c) (x2 + x) (x2 + x + 1) = 6
d) (x2 - 4x)2 - 8(x2 - 4x) + 15=0
a)4x(x-2019)-x+2019=0
b)3x(2x-3)=6-4x
giup mik nh everyone
Tìm x
a,(x+3)3-x(2x+1)2+(2x+1)(4x2-2x+1)-3x2=54
b,(x-3)3-(x-3)(x2+3x+9)+6(x+1)2+3x2=33
