You can put this solution on YOUR website!
I presume you really meant:
\n" ); document.write( " $\"+9%5E%28x-5%29+=+81%5E%28x-7%29\"$
\n" ); document.write( " $\"+9%5E%28x-5%29+=+%289%5E2%29%5E%28x-7%29\"$
\n" ); document.write( " $\"+9%5E%28x-5%29+=+9%5E%282%28x-7%29%29\"$
\n" ); document.write( " $\"+9%5E%28x-5%29+=+9%5E%282x-14%29\"$
\n" ); document.write( " $\"+x-5+=+2x-14+\"$
\n" ); document.write( " $\"+-5+=+x-14+\"$
\n" ); document.write( " $\"+9+=+x+\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
