What is (x+3) (x+3) simplified

x² + 6x + 9

Step-by-step explanation:

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

x² + 6x + 9

Step-by-step 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

x² + 6x + 9
