3.(x-2)2-25=2
\(3\cdot\left(x-2\right)^2=2+25\)
\(\Leftrightarrow3\cdot\left(x-2\right)^2=27\)
\(\Leftrightarrow\left(x-2\right)^2=9\)
\(\Leftrightarrow\orbr{\begin{cases}x-2=3\\x-2=-3\end{cases}}\Leftrightarrow\orbr{\begin{cases}x=5\\x=-1\end{cases}}\)
5-(6-x) = 4(3-2x)
co loi giai chi tiet giup minh
\(PT\Leftrightarrow5-6+x=12-8x\)
\(\Leftrightarrow9x=13\)
\(\Leftrightarrow x=\dfrac{13}{9}\)
Vậy: \(S=\left\{\dfrac{13}{9}\right\}\)
\(5-\left(6-x\right)=4\left(3-2x\right)\)
\(5-6+x=12-8x\)
\(-1+x=12-8x\)
\(x-1=12-8x\)
\(12+1=8x+1\)
\(8x=13-1\)
\(x=12:8\)
\(x=\dfrac{12}{8}=\dfrac{3}{2}\)
