We can use the discriminant to determine the number and type of solutions: \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%0D%0A+sqrt%28+9%5E2-4%2A%28-1%29%2A7+%29=sqrt%28109%29%0D%0A\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since the discriminant is real and not 0 we know that there are 2 real solutions\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ":)
\n" ); document.write( "
