\n" ); document.write( "x + 1/x =5/2
\n" ); document.write( "Multiply thru by 2x to get:
\n" ); document.write( "2x^2+2 = 5x
\n" ); document.write( "2x^2-5x+2 = 0
\n" ); document.write( "2x^2-4x-x+2=0
\n" ); document.write( "2x(x-2)-(x-2)=0
\n" ); document.write( "(x-2)(2x-1)=0
\n" ); document.write( "x = 2 or x = 1/2
