factor completely:
\n" ); document.write( " $\"8x%5E4y%5E4-18x%5E2y%5E6\"$
\n" ); document.write( "

\r\n" );
document.write( "Look for the largest whole number you can factor out of 8 and 18.\r\n" );
document.write( "This is 2.\r\n" );
document.write( "\r\n" );
document.write( "Now look for the LARGEST power of x you can factor out.  This is\r\n" );
document.write( "the SMALLEST power that occurs, but x must appear in ALL terms.\r\n" );
document.write( "This is \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now look for the LARGEST power of y you can factor out.  This is\r\n" );
document.write( "the SMALLEST power that occurs, but y must appear in ALL terms.\r\n" );
document.write( "This is \r\n" );
document.write( "\r\n" );
document.write( "So factor out \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now the expression in parentheses is the difference of two\r\n" );
document.write( "perfect squares.  is the same as  and\r\n" );
document.write( " is the same as  so that expression in\r\n" );
document.write( "parentheses factors as the sum of times difference of the bases\r\n" );
document.write( "of those perfect squares, i.e., their square roots:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
