x-1/x = square root of 5
\n" ); document.write( "Squaring both sides
\n" ); document.write( ">x^2+(1/x^2)-2=5
\n" ); document.write( ">x^2+(1/x^2)=5+2
\n" ); document.write( ">x^2+(1/x^2)=7\r
\n" ); document.write( "\n" ); document.write( "Adding 2 to both sides\r
\n" ); document.write( "\n" ); document.write( ">x^2+(1/x^2)+2=7+2
\n" ); document.write( ">(x+1/x)^2= 3^2
\n" ); document.write( "Square root of above eqn...
\n" ); document.write( "Ans x+1/x=3
\n" ); document.write( " \n" ); document.write( "
