Rewrite x2 + 5x + 6 as an equivalent expression in factored form and then factorize it using grouping and the distributive property.

3.1.3 Rewrite as an equivalent expression in the form.
From the previous steps, the trinomial is $x^2 + 5x + 6$, and the two integers are 2 and 3. To rewrite this as an equivalent expression in factored form, we use these integers:

$$x^2 + 5x + 6 = \boxed{(x + 2)(x + 3)}$$

3.1.4 Use the knowledge obtained from activity 2 on grouping and the distributive property to factorize the expression.
The expression to factorize is $x^2 + 5x + 6$.

Step 1: Rewrite the middle term, $5x$, using the two integers 2 and 3.
