If you just want to use a formula you can break it down over the Fx2 components.

(Right click on an input to change its name from x to a)

Otherwise you can use a VB.NET component to write a script to handle this

Or you could use the trnsform matrix..

...and I'm sure the last variable is meant to read c, not b. Otherwise you could just add up the coeffs.

no. sorry you misunderstand. Don't put F=

Just have your equation

You're not the first to think like this and I doubt you'll be the last. Would it be more straight forward if David implemented something like this:
