(x-3/2)^2=25/16
=>\(^{x^2}\)-3/2^2=25/16
=>x^2=25/16+3/2^2
mk chán rồi bn tự làm tiếp đi
\(\left(x-\frac{3}{2}\right)^2=\frac{25}{16}\)
\(\Rightarrow x-\frac{3}{2}=\orbr{\begin{cases}\frac{5}{4}\\-\frac{5}{4}\end{cases}}\)
\(\Rightarrow x=\orbr{\begin{cases}\frac{11}{4}\\\frac{1}{4}\end{cases}}\)
\(\left(x-\frac{3}{2}\right)^2=\frac{25}{16}\)
\(\Leftrightarrow\)\(\orbr{\begin{cases}x-\frac{3}{2}=\frac{5}{4}\\x-\frac{3}{2}=-\frac{5}{4}\end{cases}}\)
\(\Leftrightarrow\)\(\orbr{\begin{cases}x=2\frac{3}{4}\\x=\frac{1}{4}\end{cases}}\)
Vậy...
