We want factors of 40 with add up to -3
\n" ); document.write( "-8 and 5 make -40
\n" ); document.write( "8 and -5 make -40
\n" ); document.write( "8 and 5 make 40 but 8+5=13 not -3
\n" ); document.write( "It has no real roots.
\n" ); document.write( "Using the determinant
\n" ); document.write( "b^2-4ac
\n" ); document.write( "(-3)^2-4*(-8)*(-5)
\n" ); document.write( "9-160
\n" ); document.write( "-151
\n" ); document.write( "two complex roots\r
