How can I reset the Mini IPad model A1432?

Depends on what you mean by "reset" exactly.

You can go into Settings->General->Reset, and choose one of the options there depending on what you want to do.

You can press and hold both the Home and the Top (or Side) buttons for at least 10 seconds, until you see the Apple logo, and this will reboot the iPad.

Or you can follow the steps in this support document, to completely erase and restore the iPad to factory condition: Restore your iPhone, iPad, or iPod to factory settings - Apple Support

What do you mean by a reset?

A hard reset is an easy thing to do.

A hard reset of your iPad is holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.
