Question

(x-3/2)² =9/4 tìm x

Answer 1

\(\left(x-\dfrac{3}{2}\right)^2=\dfrac{9}{4}\)

\(\Rightarrow\left(x-\dfrac{3}{2}\right)^2=\left(\dfrac{3}{2}\right)^2\)

\(\Leftrightarrow x-\dfrac{3}{2}=\dfrac{3}{2}\)

\(\Rightarrow x=\dfrac{6}{2}\)

Answer 2

\(\left(x-\dfrac{3}{2}\right)^2=\dfrac{9}{4}\)

\(\left(x-\dfrac{3}{2}\right)^2=\left(\dfrac{3}{2}\right)^2\)

=>\(x-\dfrac{3}{2}=\dfrac{3}{2}\)

\(x=\dfrac{3}{2}+\dfrac{3}{2}\)

\(x=3\)
