Tìm x biết:

a) x ( x − 2008 ) − x + 2008 = 0

Roboguru Admin · Accepted Answer

x ( x − 2008 ) − x + 2008 = 0 ⇔ x ( x − 2008 ) − ( x − 2008 ) = 0 ⇔ ( x − 2008 ) ( x − 1 ) = 0 ⇔ [ x − 2008 = 0 x − 1 = 0 ​ ⇔ [ x = 2008 x = 1 ​ V ậ y x = 1 , x = 2008

Tìm x biết: a) x ( x − 2008 ) − x + 2008 = 0

Giải thích

x ( x − 2008 ) − x + 2008 = 0 ⇔ x ( x − 2008 ) − ( x − 2008 ) = 0 ⇔ ( x − 2008 ) ( x − 1 ) = 0 ⇔ [ x − 2008 = 0 x − 1 = 0 ⇔ [ x = 2008 x = 1 V ậ y x = 1 , x = 2008
