1. The problem is to add two formulas together. 2. The general formula for addition of two expressions is: $$A + B$$ where $A$ and $B$ are any algebraic expressions or formulas. 3. For example, if the formulas are $f(x) = 2x + 3$ and $g(x) = x^2 - 1$, then their sum is: $$f(x) + g(x) = (2x + 3) + (x^2 - 1)$$ 4. Simplify by combining like terms: $$= x^2 + 2x + (3 - 1) = x^2 + 2x + 2$$ 5. This shows how to add formulas by combining their terms carefully. Final answer: $$x^2 + 2x + 2$$
