Since nobody has replied, here's how I do it on a Google Nexus 7, which is also Android. However, there may be alternative methods which I haven't yet discovered, and I don't know enough to say whether it will be identical on your tablet. Anyway FWIW here goes:
At the bottom of the home screen, press the icon with six small squares in a circle. This will bring up the complete set of icons for all installed programs.
Press and hold the icon for the program you wish to uninstall. After a second or two, the word "Uninstall" should appear the top of the screen. Drag the relevant icon onto the word "Uninstall" and then confirm the operation.
