\n" ); document.write( "\n" ); document.write( "Be aware: the solution and the answer by @Theo are incorrect.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One can see it even with unarmed eye.  Indeed,  in  Theo's equation \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "             2k^2 - 3k - 4 = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the leading coefficient  \" 2 \"  is positive,  while the constant term  \" -4 \"  is negative.
\n" ); document.write( "It implies that the roots of this equation must be with opposite signs;
\n" ); document.write( "while Theo gives both roots positive at the end of his solution,  which is wrong.\r
