Giải thích các bước giải:
`|x+5|=±6`
\(\left[ \begin{array}{l}x+5=6\\x+5=-6\end{array} \right.\)
\(\left[ \begin{array}{l}x=1\\x=-11\end{array} \right.\)
Vậy ....
`|2x-1|-2^2=2016^0.(-2)^2`
`|2x-1|-2^2=1.(-2)^2`
`|2x-1|-2^2=4`
`|2x-1| -4 = 4 `
`|2x-1| = 4+4`
`|2x-1| = ±8`
\(\left[ \begin{array}{l}2x-1=8\\2x-1=-8\end{array} \right.\)
\(\left[ \begin{array}{l}x=9/2\\x=-7/2\end{array} \right.\)
Vậy .....
