Question: Factor the trinomial: 2x squared plus 5x plus 3
1. **State the problem:** Factor the trinomial $$2x^2 + 5x + 3$$.
2. **Recall the factoring formula:** For a quadratic trinomial $$ax^2 + bx + c$$, we look for two numbers that multiply to $$a \times c$$ and add to $$b$$.
3. **Calculate the product and sum:** Here, $$a = 2$$, $$b = 5$$, and $$c = 3$$.
- Product: $$2 \times 3 = 6$$
- Sum: $$5$$
4. **Find two numbers that multiply to 6 and add to 5:** These numbers are $$2$$ and $$3$$.
5. **Rewrite the middle term using these numbers:**
$$2x^2 + 2x + 3x + 3$$
6. **Group terms:**
$$(2x^2 + 2x) + (3x + 3)$$
7. **Factor each group:**
$$2x(x + 1) + 3(x + 1)$$
8. **Factor out the common binomial:**
$$(2x + 3)(x + 1)$$
**Final answer:** $$\boxed{(2x + 3)(x + 1)}$$
