Question

2x(x-2021)-x+2021=0

 

Answer 1

=>(x-2021)(2x-1)=0

=>x=2021 hoặc x=1/2

Answer 2

=>(x-2021)(2x-1)=0

=>x=2021 hoặc x=1/2

Answer 3

2x(x - 2021) - x + 2021 = 0

2x(x - 2021) - (x - 2021) = 0

(x - 2021)(2x - 1) = 0

x - 2021 = 0 hoặc 2x - 1 = 0

*) x - 2021 = 0

x = 2021

*) 2x - 1 = 0

2x = 1

x = 1/2

Vậy x = 1/2; x = 2021
