Question

\(\left(x-710\right).\left(53-x\right)=0\)

Answer 1

`(x-710)(53-x) =0`

`<=> [(x-710=0),(53-x=0):}`

`=> [(x=0+710 = 710),(x=53-0=53):}`

Answer 2

(x-710).(53-x)=0

\(< =>\left[{}\begin{matrix}x-710=0\\53-x=0\end{matrix}\right.< =>\left[{}\begin{matrix}x=710\\x=53\end{matrix}\right.\)

Vậy x∈{710,53}

Answer 3

\(\left(x-710\right).\left(53-x\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}x-710=0\\53-x=0\end{matrix}\right.\)           \(\Rightarrow\left[{}\begin{matrix}x=710\\x=53\end{matrix}\right.\)
Vậy \(x\in\left\{710;53\right\}\)

Answer 4

(x-710)(53-x)=0

Ta có 2 TH:

TH1:x-710=0

x=0+710=710

TH2:53-x=0

-x=0-53=-53

x=53

Vậy x= 53 hoặc x=710

Answer 5

\(\left(x-710\right).\left(53-x\right)=0\\ \Leftrightarrow\left\{{}\begin{matrix}x-710=0\\53-x=0\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=710\\x=53\end{matrix}\right.\)
