Non-static method Illuminate\Database\Eloquent\Model::update() should not be called statically and delete function not working

Question

1)When I tried to use Model in update function of controller I get the error? What might be the reason for it. I got error: Non-static method Illuminate\Database\Eloquent\Model::update() should not be called statically

2)Another problem is that my delete function doesn't delete the product. It redirects in another page. What might be the mistake in routes?

ProductController.php

Route for delete:

Route::delete('/products/{id}',[ProductController::class, 'delete'])->name('deleteProduct');
