Solve:
\n" ); document.write( " $\"x-sqrt%282x%2B1%29+=+7\"$ First, subtract x from both sides.
\n" ); document.write( " $\"-sqrt%282x%2B1%29+=+-x%2B7\"$ Square both sides.
\n" ); document.write( " $\"2x%2B1+=+x%5E2-14x%2B49\"$ Subtract 2x from both sides.
\n" ); document.write( " $\"1+=+x%5E2-16x%2B49\"$ Subtract 1 from both sides.
\n" ); document.write( " $\"x%5E2-16x%2B48+=+0\"$ Factor.
\n" ); document.write( " $\"%28x-12%29%28x-4%29+=+0\"$ Apply the zero product rule.
\n" ); document.write( " $\"x-12+=+0\"$ or $\"x-4+=+0\"$ so...
\n" ); document.write( " $\"highlight%28x+=+12%29\"$ or $\"highlight%28x+=+4%29\"$ \n" ); document.write( "

\n" );
