How do you factor a trinomial step by step

Factoring a trinomial involves breaking it down into simpler binomials. Let's go step by step using an example trinomial:

### Example:  
Factor the trinomial \(x^2 + 5x + 6\).

### Step-by-Step Guide:

1. **Identify the form**  
   A standard trinomial is written as \(ax^2 + bx + c\), where:
   - \(a\) is the coefficient of \(x^2\)
   - \(b\) is the coefficient of \(x\)
   - \(c\) is the constant term  
   In our example, \(x^2 + 5x + 6\), we have:
   - \(a = 1\)
   - \(b = 5\)
   - \(c = 6\)

2. **Find two numbers that multiply to give \(ac\) and add to give \(b\)**  
   Here, we need two numbers that:
   - Multiply to \(a \times c = 1 \times 6 = 6\)
   - Add up to \(b = 5\)

   The numbers that satisfy both conditions are 2 and 3 because:
   - \(2 \times 3 = 6\) (they multiply to 6)
   - \(2 + 3 = 5\) (they add to 5)

3. **Rewrite the middle term**  
   Rewrite the middle term \(5x\) as the sum of the two numbers found in the previous step:  
   \[
   x^2 + 5x + 6 = x^2 + 2x + 3x + 6
   \]

4. **Factor by grouping**  
   Group the terms in pairs:
   \[
   (x^2 + 2x) + (3x + 6)
   \]
   Now, factor out the greatest common factor (GCF) from each pair:
   \[
   x(x + 2) + 3(x + 2)
   \]

5. **Factor out the common binomial**  
   Both groups contain the common factor \((x + 2)\), so factor it out:
   \[
   (x + 2)(x + 3)
   \]

### Final Answer:
The factored form of \(x^2 + 5x + 6\) is \((x + 2)(x + 3)\).

### Recap of the steps:
1. Identify the form and coefficients.
2. Find two numbers that multiply to \(a \cdot c\) and add to \(b\).
3. Rewrite the middle term.
4. Factor by grouping.
5. Factor out the common binomial.
