Solve for x:
\n" ); document.write( "\"10a%5Ex%5E2-2abx-36b%5E2+=+0\" This can be factored.
\n" ); document.write( "\"2%285ax%2B9b%29%28ax-2b%29+=+0\" Applying the zero product principle:
\n" ); document.write( "\"5ax%2B9b+=+0\" and/or \"ax-2b+=+0\"
\n" ); document.write( "If \"5ax%2B9b+=+0\" then \"5ax+=+-9b\" so \"x+=+-%289b%29%2F5a\"
\n" ); document.write( "If \"ax-2b+=+0\" then \"ax+=+2b\" so \"x+=+2b%2Fa\"
\n" ); document.write( "
\n" );
