$\"%28x+-+1%2Fx%29%5E2=x%5E2-1-1%2B1%2Fx%5E2\"$
\n" ); document.write( " $\"%28x+-+1%2Fx%29%5E2=x%5E2%2B1%2Fx%5E2-2\"$
\n" ); document.write( "Similarly,
\n" ); document.write( " $\"%28x+%2B+1%2Fx%29%5E2=x%5E2%2B1%2Fx%5E2%2B2\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"%28x+%2B+1%2Fx%29%5E2=%28x+-+1%2Fx%29%5E2%2B4\"$
\n" ); document.write( " $\"%28x+%2B+1%2Fx%29%5E2=5%2B4\"$
\n" ); document.write( " $\"%28x+%2B+1%2Fx%29%5E2=9\"$
\n" ); document.write( " $\"x+%2B+1%2Fx=0+%2B-+3\"$ \n" ); document.write( "

\n" );
