You can put this solution on YOUR website!
x^2 + y^2 = 6xy\r
\n" ); document.write( "\n" ); document.write( "adding 2xy both sides\r
\n" ); document.write( "\n" ); document.write( "x^2 + y^2 +2xy = 8xy
\n" ); document.write( "=>(x+y)^2 = 8xy ------------- 1\r
\n" ); document.write( "\n" ); document.write( "subtracting 2xy on both sides\r
\n" ); document.write( "\n" ); document.write( "x^2 + y^2 -2xy = 4xy
\n" ); document.write( "=> (x-y)^2 = 4xy -------------2\r
\n" ); document.write( "\n" ); document.write( "dividing 1 by 2\r
\n" ); document.write( "\n" ); document.write( " $\"%28%28x%2By%29%2F%28x-y%29%29%5E2+=+2\"$ \r
\n" ); document.write( "\n" ); document.write( "so (x+y)/(x-y) = $\"%2Bsqrt%282%29\"$ and $\"-sqrt%282%29\"$ \n" ); document.write( "

\n" );
