mathcad adding two equations with one variable

Question

I checked this section for a similar question and could not locate one. It's simple one I'm guessing but I just cant figure it out.

Two equations: 3x^2 + 4x -7 and 5x^2-7x+3

(or whatever one variable equation).

How can I add them in mathcad so I get the answer 8x^2 -3x-4 ?

Thanks. Mr Noob....
