document.write( "If two vectors are non-parallel and after multiplication by scalars they become equal,\r\n" );
document.write( "it may happen in only one case:  if the scalar multipliers both are equal to 0 (ZERO).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, 2p-1 = 0, which implies p = ,\r\n" );
document.write( "\r\n" );
document.write( "and q+2 = 0, which implies q = -2.\r\n" );
