Question

(5−x)(2x− \(\dfrac{1}{3}\)) =0

Answer 1

`<=> x = 5` hoặc `2x - 1/3 = 0`

`<=> x =5` hoặc `x = 1/6`

Answer 2

\(\left(5-x\right)\left(2x-\dfrac{1}{3}\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}5-x=0\\2x-\dfrac{1}{3}=0\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}x=5\\2x=\dfrac{1}{3}\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}x=5\\x=\dfrac{1}{6}\end{matrix}\right.\)

Answer 3

`(5-x).(2x-1/3)=0`

`<=>5-x=0` hoặc `2x-1/3=0`

`<=>x=5` hoặc `2x=1/3`

`<=>x=5` hoặc `x=1/6`

Vậy `x\in{5;1/6}`
