Question

\(\left(2x-3\right)^2=9\)

Answer 1

(2x - 3)²=3²

2x-3=3

2x =3+3

2x =6

x =6 : 2

x=3

Vậy x = 3

NHỚ TICK ĐẤY!

Answer 2

\(\left(2x-3\right)^2=9\)

\(\Rightarrow\left[{}\begin{matrix}2x-3=3\\2x-3=-3\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=3\\x=0\end{matrix}\right.\)

Vậy x = 3 hoặc x = 0

Answer 3

Cho mình thêm 1 chút xíu:

(2x - 3)²=(-3)²

2x - 3 =-3

2x = =-3+3

2x=0

x = 0

Vậy x = 0
