If the F(x)=2x+1 , g(x)=√X Founding the following

a) F(x)- g(x)

b) F(x) + g(x)

What is the problem here?

$\displaystyle F(x) - g(x) = (2x + 1) - \sqrt{x}$

$\displaystyle F(x) + g(x) = (2x + 1) + \sqrt{x}$

I want to know the final product

Reached a solution but not the resolve convincingly

What do you mean? As far as simplifying the expressions, it can't be done. The forms I gave you are as simplified as they get. They are the "final product."

the values for x are not given so you are not able to simplify more.
