Question

\(\left(2x-4^2\right)=16\)

Answer 1

Câu hỏi bị lỗi rồi nhé!

Answer 2

(2x - 4²) = 16

<=> 2(x - 8) = 16

<=> x - 8 = 8

<=> x = 16

Answer 3

\(\left(2x-4\right)^2=16\)

\(\Leftrightarrow\left[{}\begin{matrix}2x-4=4\\2x-4=-4\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=4\\x=0\end{matrix}\right.\)
