You can put this solution on YOUR website!
discriminant D is $\"b%5E2-4ac\"$ where a,b are the coefficents of $\"x%5E2\"$ ,x,and c is the constant.

\n" ); document.write( " $\"3r%5E2%2B10=-7r-7r%5E2\"$
\n" ); document.write( ":
\n" ); document.write( " $\"10r%5E2%2B7r%2B10=0\"$
\n" ); document.write( ":
\n" ); document.write( " $\"D=7%5E2-4%2810%29%2810%29\"$
\n" ); document.write( ":
\n" ); document.write( " $\"D=49-400=-351\"$
\n" ); document.write( ":
\n" ); document.write( "when D is less than zero the solutions will be complex and there will be 2 solutions \n" ); document.write( "

\n" );
