\n" );
document.write( "\"1%2F%281-x%29%2B1%2F%281%2Bx%29=4+\"   |Multiply thru by\"%281-x%29%281%2Bx%29\"so as all denominators = 1
\n" );
document.write( " (1+x)  + (1-x) = 4(1-x^2)
\n" );
document.write( "2 = 4-4x^2)
\n" );
document.write( " 4x^2 = 2
\n" );
document.write( "  x^2 = 1/2
\n" );
document.write( "  x^4 = 1/4 \n" );
document.write( "
\n" );
