1. **State the problem:** Solve the equation $$\log(2x + 3) + \log(x + 2) - 1 = 0$$ for $x$.
2. **Use the logarithm property:** The sum of logarithms is the logarithm of the product:
$$\log a + \log b = \log(ab)$$
So,
$$\log(2x + 3) + \log(x + 2) = \log\big((2x + 3)(x + 2)\big)$$
3. **Rewrite the equation:**
$$\log\big((2x + 3)(x + 2)\big) - 1 = 0$$
4. **Isolate the logarithm:**
$$\log\big((2x + 3)(x + 2)\big) = 1$$
5. **Convert from logarithmic to exponential form:**
Since the base of the logarithm is 10 (common log),
$$ (2x + 3)(x + 2) = 10^1 = 10 $$
6. **Expand the product:**
$$ 2x^2 + 4x + 3x + 6 = 10 $$
$$ 2x^2 + 7x + 6 = 10 $$
7. **Bring all terms to one side:**
$$ 2x^2 + 7x + 6 - 10 = 0 $$
$$ 2x^2 + 7x - 4 = 0 $$
8. **Solve the quadratic equation using the quadratic formula:**
$$ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$
where $a=2$, $b=7$, $c=-4$.
Calculate the discriminant:
$$ \Delta = 7^2 - 4 \times 2 \times (-4) = 49 + 32 = 81 $$
Calculate the roots:
$$ x = \frac{-7 \pm \sqrt{81}}{2 \times 2} = \frac{-7 \pm 9}{4} $$
9. **Find the two solutions:**
$$ x_1 = \frac{-7 + 9}{4} = \frac{2}{4} = 0.5 $$
$$ x_2 = \frac{-7 - 9}{4} = \frac{-16}{4} = -4 $$
10. **Check the domain restrictions:**
The arguments of the logarithms must be positive:
$$ 2x + 3 > 0 \Rightarrow x > -\frac{3}{2} = -1.5 $$
$$ x + 2 > 0 \Rightarrow x > -2 $$
So the domain is $x > -1.5$.
Check $x_1 = 0.5$: valid.
Check $x_2 = -4$: invalid (less than -1.5).
11. **Final answer:**
$$ \boxed{0.5} $$
