Answer 3

To solve the equation $(x + 5) - x^2 = (2 - x)(2 + x)$, let's follow these steps:

1. Distribute the right-hand side: $(x + 5) - x^2 = 4 - x^2$.

2. Combine like terms on the left-hand side: $x + 5 - x^2 = 4 - x^2$.

3. Add $x^2$ to both sides to isolate the $x$ term: $x + 5 = 4$.

4. Subtract 5 from both sides: $x = -1$.

So, the solution to the equation is $x = -1$.
