Step 2.1

Factor $a + 3$ out of ${(a + 3)}^{2}$ .

$(a + 3) (a + 3) - a (a + 3)$

Step 2.2

Factor $a + 3$ out of $- a (a + 3)$ .

$(a + 3) (a + 3) + (a + 3) (- a)$

Step 2.3

Factor $a + 3$ out of $(a + 3) (a + 3) + (a + 3) (- a)$ .

$(a + 3) (a + 3 - a)$

Step 3

Subtract $a$ from $a$ .

$(a + 3) (0 + 3)$

Step 4

Add $0$ and $3$ .

$(a + 3) \cdot 3$
