(x-1/2)^2 = 16
(x-1/2)^2 = 4^ 2
x-1/2 = 4
x= 4,5
\(\Rightarrow\left(x-\frac{1}{2}\right)^2=4^2\)
\(\Rightarrow\orbr{\begin{cases}x-\frac{1}{2}=4\\x-\frac{1}{2}=-4\end{cases}\Rightarrow\orbr{\begin{cases}x=\frac{9}{2}\\x=-\frac{7}{2}\end{cases}}}\)
tíc mình nha
\(\left(x-\frac{1}{2}\right)^2=16\)
\(\left(x-\frac{1}{2}\right)^2=4^2\)
\(\left(x-\frac{1}{2}\right)=4\)
\(x=4+\frac{1}{2}\)
\(x=4,5\)
\(\left(x-\frac{1}{2}\right)^2=16\)
\(\left(x-\frac{1}{2}\right)^2=4^2\)
\(\Leftrightarrow\orbr{\begin{cases}x-\frac{1}{2}=4\\x-\frac{1}{2}=-4\end{cases}}\)\(\Rightarrow\orbr{\begin{cases}x=\frac{9}{2}\\x=-\frac{7}{2}\end{cases}}\)
