Translating the problem description into algebra:\r
\n" ); document.write( "\n" ); document.write( "\"%283%2F4%29n%5E2+=+5n-3\" Simplify and solve for n. Mutliply through by 4 to clear the fraction.
\n" ); document.write( "\"3n%5E2+=+20n-12\" Simplify.
\n" ); document.write( "\"3n%5E2-20n%2B12+=+0\" Solve the quadratic equation by factoring.
\n" ); document.write( "\"%283n-2%29%28n-6%29+=+0\" Apply the zero products principle.
\n" ); document.write( "\"3n-2+=+0\" and/or \"n-6+=+0\"
\n" ); document.write( "If \"3n-2+=+0\" then \"3n+=+2\" and \"n+=+2%2F3\" Discard this solution because you are looking for an integer.
\n" ); document.write( "If \"n-6+=+0\" then \"n+=+6\" This is the required integer.\r
\n" ); document.write( "\n" ); document.write( "Check:\r
\n" ); document.write( "\n" ); document.write( "\"%283%2F4%296%5E2+=+%283%2F4%2936\" = 27
\n" ); document.write( "\"5%286%29-3+=+30-3\" = 27\r
\n" ); document.write( "\n" ); document.write( "
