Question

Tìm x, biết :

x . ( x - 2023 ) = 0

Answer 1

`@` `\text {Ans}`

`\downarrow`

`x(x-2023) = 0`

`=>`

`TH1: x = 0`

`TH2: x - 2023 = 0`

`=> x = 0 + 2023`

`=> x = 2023`

Vậy, `x \in {0; 2023}.`

Answer 2

x.(x - 2023) = 0

⇒ x = 0 hoặc x - 2023 = 0

*) x - 2023 = 0

x = 0 + 2023

x = 2023

Vậy x = 0; x = 2023
