1. **State the problem:** We need to find the result when the expression $$(x + 8)^2$$ is subtracted from $$(x + 7)$$ and write the answer as a simplified polynomial in standard form.
2. **Write the expression:** The problem can be written as:
$$ (x + 7) - (x + 8)^2 $$
3. **Recall the formula for squaring a binomial:**
$$(a + b)^2 = a^2 + 2ab + b^2$$
4. **Apply the formula to $$(x + 8)^2$$:**
$$ (x + 8)^2 = x^2 + 2 \cdot x \cdot 8 + 8^2 = x^2 + 16x + 64 $$
5. **Substitute back into the expression:**
$$ (x + 7) - (x^2 + 16x + 64) $$
6. **Distribute the subtraction:**
$$ x + 7 - x^2 - 16x - 64 $$
7. **Combine like terms:**
$$ -x^2 + (x - 16x) + (7 - 64) = -x^2 - 15x - 57 $$
8. **Write the final answer in standard polynomial form:**
$$ \boxed{-x^2 - 15x - 57} $$
This is the simplified polynomial after subtracting $$(x + 8)^2$$ from $$(x + 7)$$.
