Hide page title on one page in twenty fourteen theme

hope you have a child theme already – if not start by creating one; http://codex.wordpress.org/Child_Themes

‘full-width.php’ calls a template content-page.php via this line: get_template_part( ‘content’, ‘page’ );

you could edit content-page.php in your child theme to conditionally hide the title;

the code is in this line:
the_title( '<header class="entry-header"><h1 class="entry-title">', '</h1></header><!-- .entry-header -->' );

are you familiar with conditional statements and the conditional tag is_page() http://codex.wordpress.org/Function_Reference/is_page ?
