Question

Tìm x biết :

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

Answer 1

`# \text {DNamNgV}`

`(x - 2)*(x - 3) = 0`

`=>`

TH1: `x - 2 = 0`

`=> x = 0 + 2`

`=> x = 2`

TH2: `x - 3 = 0`

`=> x = 0 + 3`

`=> x = 3`

Vậy, `x \in {2; 3}.`

Answer 2

`(x-2)(x-3)=0`

`@TH 1`

`x-2=0`

`=>x=0+2`

`=>x=2`

`@ TH2`

`x-3=0`

`=>x=0+3`

`=>x=3`
