Answer:

(a + 2)²

Solution:

Step-by-step:

Step 1: Use the sum-product pattern

a2 +4a + 4

a2 + 2a + 2a +4

Step 2: Common factor from the two pairs

a2 + 2a + 2a + 4

a(a + 2) + 2(a + 2)

Step 3: Rewrite in factored form

a(a + 2) + 2(a + 2)

(a + 2)(a + 2)

Step 4: Combine to a square

(a + 2)(a + 2)

(a + 2)2

Answer:

(a + 2)2

yung mga ibang two po squared po pa brainliest na lng po :D
