Zooming by it self in Safari, and touchpad not working

So my touchpad is not working= Slow, and the mouse moves by itself little.

And it is zooming in by itself when I am in safari(Zooming in every min or so)

I tried everything. Vacuumed the keyboards little, formated the macbook so I could be sure it is not a software problem and so on...

What can I do? Should I try to open the macbook and see if there is dirt/dust under the touchpad?

If not. Should i just try to turn off the touchpad and use my mouse instead? And if so, how?

MacBook Pro (13-inch Mid 2012)

Try with an external point device (USB or Bluetooth)

Has the Mac gotten wet?

Is the battery swollen? If so it can put force on the trackpad causing problems like you are seeing.

- Try resetting the SMC and NVRAM/PRAM

Then format the startup disk and do a fresh install of OSX

Hello!

It works with USB mouse. but it still zooms by it self.

I tried safe mode, and it was problem anyhows. The reboot/formatation/Delate and install OMX did not remove the problem. The batteri is not swollen under so I can see it, and the touchpad is not visibly swollen either.

Should i try to open my macbook and look for dirt? Can I make the touchpad uninstall? (I think the zoom is because it might think i use 3 fingers to zoom on it)

Of the causes and actions listed in llaass's excellent response, I see your symptoms most likely pointing to a swelling battery. If so it requires immediate attention from a Apple Retail store or authorized service provider. Swelling can advance rapidly so any delay could result in additional and potentially irreparable damage to the computer.
