You can put this solution on YOUR website!
Discriminant: \"b%5E2+-+4ac\"
\n" ); document.write( "\"x%5E2+-+8x+%2B+7+=+0\"
\n" ); document.write( "a=1 b=-8 c=7
\n" ); document.write( "\"b%5E2+-+4ac\"
\n" ); document.write( "\"64+-+28\"
\n" ); document.write( "\"36\"
\n" ); document.write( "Since the disciminant is positive, there are two real solutions.
