Form::model basically populates the input fields with data either from old input or given model's attributes. So the basic form can be written like this.
<form action="/edit-account" method="POST">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="hidden" name="_method" value="PUT">
...
</form>
And then for populating the data, you can use old helper function and then check for errors.
So a basic input block will look like this.
<input type="text" name="name" value="{{ old('name', $user->name) }}">
@if ($errors->has('name'))
<strong>{{ $errors->first('name') }}</strong>
@endif
