Solve for n:
\n" ); document.write( " $\"3n%5E2-15+=+-4n\"$ Add 4n to both sides.
\n" ); document.write( " $\"3n%5E2%2B4n-15+=+0\"$ Factor.
\n" ); document.write( " $\"%283n-5%29%28n%2B3%29+=+0\"$ Apply the zero product rule.
\n" ); document.write( " $\"3n-5+=+0\"$ or $\"n%2B3+=+0\"$ so...
\n" ); document.write( " $\"3n+=+5\"$ and $\"highlight%28n+=+5%2F3%29\"$ or
\n" ); document.write( " $\"highlight%28n+=+-3%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
