Question

Tìm x :

  \(\left(x-5\right).\left(x-6\right)=0\)

Answer 1

\(\left(x-5\right)\left(x-6\right)=0\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=0+5\\x=0+6\end{array}\right.\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=5\\x=6\end{array}\right.\)

Answer 2

\(\left(x-5\right).\left(x-6\right)=0\)

Tại đây sẽ có hai trường hợp xảy ra :

\(\Leftrightarrow\left[\begin{array}{nghiempt}x-5=0\\x-6=0\end{array}\right.\)

\(\Leftrightarrow\left[\begin{array}{nghiempt}x=0+5\\x=0+6\end{array}\right.\Leftrightarrow\left[\begin{array}{nghiempt}x=5\\x=6\end{array}\right.\)

Vậy \(x\in\left\{5;6\right\}\) thõa mãn 

Answer 3

\(\left(x-5\right).\left(x-6\right)=0\)

ta xét 2 trường hợp:

<=>\(\left[\begin{array}{nghiempt}x-5=0\\x-6=0\end{array}\right.\)

<=>\(\left[\begin{array}{nghiempt}x=0+5\\x=0+6\end{array}\right.\)<=>\(\left[\begin{array}{nghiempt}x=5\\x=6\end{array}\right.\)

vậy \(x\in\left\{5,6\right\}\) thỏa mãn

 

Answer 4

\(\left(x-5\right).\left(x-6\right)=0\)

\(\Rightarrow x-5=0\) hoặc \(x-6=0\)

+) \(x-5=0\Rightarrow x=5\)

+) \(x-6=0\Rightarrow x=6\)

Vậy \(x=5\) hoặc \(x=6\)
