You can put this solution on YOUR website!
You didn't give an example, so use
\n" ); document.write( " $\"%28a+%2B+bi%29%5E2\"$
\n" ); document.write( "= $\"a%5E2+%2B+2abi+-+b%5E2\"$
\n" ); document.write( "= $\"a%5E2-b%5E2+%2B+2abi\"$
\n" ); document.write( "-----------------------
\n" ); document.write( " $\"%283+%2B+4i%29%5E2\"$
\n" ); document.write( "= $\"9+-+16+%2B+24i\"$
\n" ); document.write( "= -7 + 24i
\n" ); document.write( " \n" ); document.write( "

\n" );
