Question

(2x - 6) . (3x - 18 ) = 0

Answer 1

(2x-6).(3x-18)=0

<=> 2x-6=0 hoac 3x-18=0

<=> x=3hoac x=6

Answer 2

\(\left(2x-6\right).\left(3x-18\right)=0\)

\(\Rightarrow\hept{\begin{cases}2x-6=0\\3x-18=0\end{cases}\Rightarrow\hept{\begin{cases}2x=6\\3x=18\end{cases}\Rightarrow}\hept{\begin{cases}x=2\\x=6\end{cases}}}\)

Answer 3

2x-6=0 hoặc 3x-18=0

Th1:2x-6=0

       2x=6

          x=3

Th2:3x-18=0

       3x=18

          x=6
