Solve:
\n" ); document.write( " $\"y%5E2-8y%2B16+=+49\"$ Subtract 49 from both sides.
\n" ); document.write( " $\"y%5E2-8y-33+=+0\"$ Factor the trinomial.
\n" ); document.write( " $\"%28y%2B3%29%28y-11%29+=+0\"$ Apply the zero product property.
\n" ); document.write( " $\"y%2B3+=+0\"$ or $\"y-11+=+0\"$
\n" ); document.write( "If $\"y%2B3+=+0\"$ Subtract 3 from both sides.
\n" ); document.write( " $\"y+=+-3\"$ This is one solution.
\n" ); document.write( "If $\"y-11+=+0\"$ Add 11 to both sides.
\n" ); document.write( " $\"y+=+11\"$ This the other solution. \n" ); document.write( "

\n" );
