Question

(x-5) .(x-3)=0

Answer 1

Ta có : \(\left(x-5\right).\left(x-3\right)=0\)

\(\Leftrightarrow x-5=0\) hoặc \(x-3=0\)

\(\left(+\right)x-5=0\Leftrightarrow x=5\)

\(\left(+\right)x-3=0\Leftrightarrow x=3\)

Vậy \(x=5;x=3\)

Answer 2

(x-5).(x-3)=0

=>x-5=0 hoặc x-3=0

+)Nếu x-5=0

=>x=0+5=5

+)Nếu x-3=0

=>x=0+3=3

Vậy x=5 hoặc x=3

Answer 3

\(\left(x-5\right)\cdot\left(x-3\right)=0\)

x - 5 = 0

x = 5

x - 3 = 0

x = 3

\(x\hept{\begin{cases}5\\3\end{cases}}\)

Answer 4

( x - 5 ) . ( x - 3 ) = 0

x - 5 = 0 ; x - 3 = 0

=> x = 5 + 0 ; x = 3 + 0

=> x = 5 ; x = 3

Answer 5

(x-5)+(x-3)=0

=> x-5=0 hoac x-3=0

     x=0+5         x=0+3

       x=5          x=3

Zay x=5 hoac x=3

Answer 6

(x-5).(x-3)=0

x-5=0;x-3=0

Suy ra x=5+0;x=3+0

Vậy x=5 hoặc x=3.

Answer 7

( x - 5 ) . ( x - 3 ) = 0

x - 5 = 0 ; x - 3 = 0

=> x = 5 + 0 ; x = 3 + 0

=> x = 5 ; x = 3

Answer 8

\(\text{Ta có: ( x - 5 ) . ( x - 3 ) = 0}\)

\(\Leftrightarrow\orbr{\begin{cases}x-5=0\\x-3=0\end{cases}}\)

\(\Leftrightarrow\orbr{\begin{cases}x=0+5\\x=0+3\end{cases}}\)

\(\Leftrightarrow\orbr{\begin{cases}x=5\\x=3\end{cases}}\)
