Answer 1

(x+3)²

Explanation:

1) Expand the square.

(x+3)²

(x+3)(x+3)

2) Distribute.

(x+3)(x+3)

x(x+3)+3(x+3)

3) Distribute.

x(x+3)+3(x+3)

x² + 3x + 3x + 9

4) Combine like terms.

x² + 3x + 3x + 9

x²+6x+9

5) Use the sum-product pattern.

(x+3)²

x²+3x+3x+9

6) Common factor from the two pairs.

x²+3x+3x+9

x(x+3)+3(x+3)

7) Rewrite in factored form.

x(x+3)+3(x+3)

(x+3)(x+3)

8) Combine to a square.

(x+3)(x+3)

(x+3)²
