Question

x×x/6=24/25

Answer 1

\(\frac{x.x}{6}=\frac{24}{25}\Rightarrow25.x^2=24.6=144\Rightarrow x^2=\frac{144}{25}=\left(\frac{12}{5}\right)^2=\left(-\frac{12}{5}\right)^2\)

=> x =12/5 hoặc x = -12/5 

Answer 2

\(x\times\frac{x}{6}=\frac{24}{25}\)

\(x=\frac{24}{25}:\frac{x}{6}\)

\(x=\frac{84}{25x}\)

\(25x^2=84\)

\(x^2=3,36\)

\(x=\frac{2\sqrt{21}}{5}\)
