\n" ); document.write( "multiply numerator and denominator by (√x-√y). This makes the denominator a difference of squares.
\n" ); document.write( "[(√x-√y)/(√x+√y)][(√x-√y)(√x-√y)]
\n" ); document.write( "[(√x-√y)/(√x-√y)][(√x+√y)(√x-√y)]
\n" ); document.write( "[(√x-√y)^2][(x-y)] \n" ); document.write( "

\n" );
