    Try to write everything down step by step. Begin with surdawi's idea:\[32x^2=50 \rightarrow x^2=\frac{ 32 }{ 50 }\]You could now go on and take the root straightwawy, but it is much better to simplify the fraction first!\[x^2=\frac{ 32 }{ 50 }=\frac{ 16 }{ 25 }=\frac{ 4^2 }{ 5^2 }\]Now I think you can see the two numbers that satisfy the equation!

    Sorry, typo! I did it upside down :( It is of course:\[x^2=\frac{ 50 }{ 32 }=\frac{ 25 }{ 16 }=\frac{ 5^2 }{ 4^2 }\]
