Question

3x^2-x=0

 

Answer 1

Đề bài yêu cầu gì vậy em?

Answer 2

????

Answer 3

3x²-x=0

⇒x(3x-1)=0

⇒hoặc x=0

3x-1=0⇒x=1/3

Answer 4

\(3x^2-x=0\)

\(\Leftrightarrow x\left(3x-1\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\3x-1=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{1}{3}\end{matrix}\right.\)

Vậy pt có 2 nghiệm x = 0 hoặc x= \(\dfrac{1}{3}\)

Answer 5

Ta có: \(3x^2-x=0\)

\(\Leftrightarrow x\left(3x-1\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{1}{3}\end{matrix}\right.\)
