Answer:
x² + 6x + 9
Explanation:
If you multiply them together, they would result as an expand form but you can simplify it in its simplest terms.
(x + 3)(x + 3)
x² + 3x + 3x + 9
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 3) + 3(x + 3) ← distribute both parenthesis
= x² + 3x + 3x + 9 ← collect like terms
= x² + 6x + 9
