x^2+bx+10=0
\n" ); document.write( ".
\n" ); document.write( "b^2-4ac is the discriminant. It can't be less than zero and have real roots.
\n" ); document.write( "a=1, c=10
\n" ); document.write( "b^2-40 discriminant
\n" ); document.write( "b^2= 40
\n" ); document.write( "b=+-2sqrt(10)
\n" ); document.write( "\"-2sqrt%2810%29%3Cb%3C2sqrt%2810%29\" values of b with no real roots.
