dell inspiron 15 7659 's touchpad (right and left click on the same )

Hello guys , I have little question about dell inspiron 15 7659 's touchpad/trackpad can I use it to click on the right  and left button on the same time or my laptop is defected I know the click button can only click left or right so it's impossible to click right and left on the same time so I am asking if is it possible to click on the  right button of the touchpad and clack on the touchpad (not the button) which is equal to the right button click ... 

okay hope I did explain my question well and thank you for helping in advance
