You can put this solution on YOUR website!
Divide and conquer! Split this up and you will get it.\r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2-2%2Ax%2Ay%2By%5E2\"$ is the first part. This is a simple expansion of
\n" ); document.write( " $\"%28x-y%29%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( "The second part: $\"a%5E2-2%2Aa%2Ab-b%5E2\"$ is a simple expansion of
\n" ); document.write( " $\"%28a%2Bb%29%5E2\"$ if you first factor out a -1, which is already in the problem.
\n" ); document.write( " $\"-1%2A%28a%5E2%2B2%2Aa%2Ab%2Bb%5E2%29\"$ This is done when you put your parentheses around the second polynomial $\"a%5E2-2%2Aa%2Ab-b%5E2\"$
\n" ); document.write( "So, the factored version is
\n" ); document.write( " $\"%28x-y%29%5E2-%28a%2Bb%29%5E2\"$ \n" ); document.write( "

\n" );
