You can put this solution on YOUR website!
$\"log%282%2Cx%29+=+log%282%2Cx%5E2-6%29\"$
\n" ); document.write( " $\"x+=+x%5E2-6\"$
\n" ); document.write( " $\"0+=+x%5E2-x-6\"$
\n" ); document.write( "factoring:
\n" ); document.write( " $\"0+=+%28x-3%29%28x%2B2%29\"$
\n" ); document.write( "x = {-2, 3}
\n" ); document.write( "But, testing for extraneous solutions, we throw out the negative solution leaving:
\n" ); document.write( "x = 3
\n" ); document.write( " \n" ); document.write( "
