-4x^2+2x-1
\n" ); document.write( "using the quadratic equation {{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} we get:
\n" ); document.write( "x=(-2+-sqrt[2^2-4*-4*-1])/2*-4
\n" ); document.write( "x=(-2+-sqrt[4-16])/8
\n" ); document.write( "x=(-2+-sqrt-2)/8
\n" ); document.write( "x=(-2+-3.464i/8
\n" ); document.write( "x=-.25+-.433i answer. \n" ); document.write( "

\n" );
