Question

giải gùm em với ạ

Answer 1

\(\left|2.x-2\right|-3,75=\left(-0,5\right)^2\)

\(< =>\left|2.x-2\right|-3,75=0,25\)

\(< =>\left|2.x-2\right|=0,25+3,75\)

\(< =>\left|2.x-2\right|=4\)

\(< =>\left[{}\begin{matrix}2.x-2=4\\2.x-2=-4\end{matrix}\right.< =>\left[{}\begin{matrix}2.x=4+2\\2.x=-4+2\end{matrix}\right.\)

\(< =>\left[{}\begin{matrix}2.x=6\\2.x=-2\end{matrix}\right.< =>\left[{}\begin{matrix}x=6:2\\x=-2:2\end{matrix}\right.< =>\left[{}\begin{matrix}x=3\\x=-1\end{matrix}\right.\)

Vậy ...........
