Laravel delete button throwing out error "page couldn't be found

this is my code

view

<form action="/categories/ " method="POST">
    
    

    <button>Delete Task</button>
</form>

controller method

public function destroyCategory($id)
{

    Categories::findOrFail($id)->delete();

    return redirect('/categories');
}

route

Route::post('categories','FilesController@destroyCategory');

Form is in partial view, can that be a problem
