This was a good one; just thought i would share...of course i know this forum has smart people who may probably come up with a different approach...it took me a few minutes to figure out ...and then alas! saw the magic...

##\sqrt{\dfrac {x^2+15t-3}{x^2}}=5t##

...

##x(5t+1)(5t-1)=15t-3##

##x=\dfrac{3}{5t+1}##

Bingo!

##\sqrt{\dfrac {x^2+15t-3}{x^2}}=5t##

...

##x(5t+1)(5t-1)=15t-3##

##x=\dfrac{3}{5t+1}##

Bingo!
