How to delete unwanted items in launchpad

I can't stand using Google Chrome on a mac but is my favorite browser otherwise. I had to install it for a few mins. to download something off of a specific website the other day.

I then uninstalled Chrome and now I have these other icons still in the launchpad and hopefully not still on my computer. When I click them they just get some window that pops up saying it can't open.

How do I remove these unwanted icons that google chrome put in my launchpad? If I click and hold until the "jiggle" no "x" comes up. If I try to drag to trash it doesn't delete. If I search in spotlight and drag to trash it does nothing.

Is there a free app to help delete these icons? Ever since I've started trying Mac i've been getting these annoyning little issues like this.

How long can this go on for lol.

Thanks for any help.
