Question

4x^2-2x=0

Answer 1

4x^2-2x=0

2x(2x-1)=0

2x-1=0

2x=1

x=1/2

Vậy x=1/2

Answer 2

Answer 3

4x-2x=0

2x(2x-1)=0

suy ra 2x=0 hoặc 2x-1=0

suy ra x=0 hoặc x=1/2

Answer 4

Ta có: \(4x^2-2x=0\)

\(\Leftrightarrow2x\left(2x-1\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=\dfrac{1}{2}\end{matrix}\right.\)
