\n" ); document.write( " $\"y%5E2%2B10y%2B25%2B2y%5E2-4%28-%28y%2B5%29%29%2B6y-5=0\"$
\n" ); document.write( " $\"y%5E2%2B10y%2B25%2B2y%5E2%2B4y%2B20%2B6y-5=0\"$
\n" ); document.write( " $\"3y%5E2%2B20y%2B40=0\"$
\n" ); document.write( "This equation has no real solutions.
\n" ); document.write( "So there is no solution to the system.
