document.write( "If a parabola has equation  (is presented in the form)  y = \"%281%2F%284p%29%29%2Ax%5E2\",\r\n" );
document.write( "\r\n" );
document.write( "then the focal point is  F = (0,p).\r\n" );

document.write( "In this problem,  y = \"%281%2F%28-10%29%29%2Ax%5E2\",  so  4p = -10;  THEREFORE,  p = \"-10%2F4\" = -2.5.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "HENCE, the focal point is  F = (0,-2.5).\r\n" );
