1. **State the problem:** Solve the quadratic equation $$2x^2 + 7x + 3 = 0$$ by factorization.
2. **Recall the factorization method:** For a quadratic equation $$ax^2 + bx + c = 0$$, we look for two numbers that multiply to $$a \times c$$ and add to $$b$$.
3. **Calculate product and sum:** Here, $$a = 2$$, $$b = 7$$, and $$c = 3$$.
Calculate product: $$a \times c = 2 \times 3 = 6$$.
We need two numbers that multiply to 6 and add to 7. These numbers are 6 and 1.
4. **Rewrite the middle term:** Split the middle term using 6 and 1:
$$2x^2 + 6x + 1x + 3 = 0$$
5. **Group terms:**
$$(2x^2 + 6x) + (1x + 3) = 0$$
6. **Factor each group:**
$$2x(x + 3) + 1(x + 3) = 0$$
7. **Factor out the common binomial:**
$$(2x + 1)(x + 3) = 0$$
8. **Apply zero product property:** Set each factor equal to zero:
$$2x + 1 = 0$$ or $$x + 3 = 0$$
9. **Solve each equation:**
For $$2x + 1 = 0$$:
$$2x = -1$$
$$x = \frac{\cancel{2}x}{\cancel{2}} = \frac{-1}{2}$$
For $$x + 3 = 0$$:
$$x = -3$$
**Final answer:** $$x = -\frac{1}{2}$$ or $$x = -3$$
