Question

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

TÌM x

giúp mình với nhé!!!

Answer 1

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

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

\(\Rightarrow\dfrac{3}{4}-x=\dfrac{2}{3}\Rightarrow x=\dfrac{1}{12}\)

Answer 2

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

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

\(\Rightarrow\)\(\dfrac{3}{4}-x=\dfrac{2}{3}\)

\(x=\dfrac{3}{4}-\dfrac{2}{3}\)

\(x=\dfrac{1}{12}\)

Answer 3

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

\(\Rightarrow\dfrac{3}{4}-x=\dfrac{2}{3}\Rightarrow-x=\dfrac{2}{3}-\dfrac{3}{4}=\dfrac{-1}{12}\)

\(\Rightarrow x=\dfrac{1}{12}\)
