\(3x\left(x-1\right)+x-1=0\)
\(\Leftrightarrow\left(x-1\right)\left(3x+1\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}x=1\\x=-\dfrac{1}{3}\end{matrix}\right.\)
Tìm x
a)3x(x-2)+2(2-x)=0
b)5x(3x-1)+x(3x-1)-2(3x-1)=0
Tìm x :
a) 3x(x-1)+x-1=0
b)2(x+3)-x^2 - 3x = 0
Bài 4: Tìm x:
1) x2 - 9x = 0 2) x(x - 4) – x2 = 7 3) 3x + 2(x – 5) = 5
4) 25x2 - 1 = 0 5) 3x(x - 2) - 5(x - 2) = 0 6) 3x(x - 7) + 4(x – 7) = 0
7) 4x2 – 9 = 0 8) 10x(x - 4) + 2x - 8 = 0 9) x(2x - 5) - 2x2 = 0
10) 2x2 – 4x = 0 11) 2x(3 - 4x) + 3(4x - 3) = 0 12) 2x (x – 5) – 2x2 = 3
mọi người giúp mình vs chiều 1g mình thi rồi! cảm ơn!
Tìm x:
A/ 5x²(3x-1)-10x³(1-3x) = 0
B/ 9x(x-3)+18x²(3-x) - 81x²(x-3) = 0
C/ (4x-1)(3x-5)-x(4x-1) = 3(1-4x)
D/ 2x²(3x+1)+7(3x+1) = 2x(3x+1)
BT2: Tìm x 2, 3x(x-4)+2x-8=0 3, 4x(x-3)+x^2-9=0 4, x(x-1)-x^2+3x=0 5, x(2x-1)-2x^2+5x=16
Tìm x biết:
