Question

(x+3).(x-2)=0

 

Answer 1

(x + 3).(x - 2) = 0

=> \(\left[\begin{array}{nghiempt}x+3=0\\x-2=0\end{array}\right.\)=> \(\left[\begin{array}{nghiempt}x=-3\\x=2\end{array}\right.\)

Vậy \(\left[\begin{array}{nghiempt}x=-3\\x=2\end{array}\right.\)

Answer 2

x = 2 

 

Answer 3

(x+3).(x-2)=0

=> x+3=0 hoặc x-2=0

=>x=0-3 hoặc x= 0+2

=> x=-3 hoặc x=2

Vì -3< 2 nên x=2

Answer 4

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

\(\Rightarrow\)\(x+3\)=0 hoặc \(x\)-2=0

Nếu \(x\)+3=0

       \(x\)=0-3

       \(x\)=-3

Nếu \(x\)-2=0

        \(x\)=0+2 

        \(x\)=2

Vậy \(x\)=-3 hoặc \(x\)=2.
