\n" );
document.write( " P(x)=-2x^2+7x+8
\n" );
document.write( "     = -2(x - 7/4)^2 + 49/8 + 64/8
\n" );
document.write( "    0 = -2(x - 7/4)^2 + 113/8
\n" );
document.write( "   113/16 = (x-7/4)^2
\n" );
document.write( "   7/4 ± sqrt(113)/4 = x
\n" );
document.write( "   1.75 ± 2.6575 = x
\n" );
