Answer 1

It happens because you've misplaced the ', you should pass the value correctly in return
replace your edit method with this:
public function edit($id)
{
$category = Category::find($id);
return view('admin.categories.edit', ['category' => $category]);
}

Answer 2

When posting code try to make it as readable as possible. Easiest way to accomplish that is to read the WHOLE post before you post it.
On the issue:
In the CategoriesController#edit reaplace
['category=>$category']
with
['category'=>$category]
Also in this scenario you can use the
compact('category')
instead of the array as the variable $category and the key in the array 'category' have same name.

Answer 3

it's simple as you know!
just replace in your edit function
return view('admin.categories.edit', ['category=>$category']);
with:
return view('admin.categories.edit')->withCategory($category);
