Step-by-step explanation:

Step 1: Define

x² + 6x + 9

Step 2: Find Roots α and β

Factor quadratic:                  (x + 3)²Find roots:                             α = -3, β = -3

Step 3: Solve

Apply negatives:                    -α = -(-3), -β = -(-3)Multiply:                                  -α = 3, -β = 3Write binomial factor:            (x - 3)²Expand [FOIL]:                       x² - 6x + 9
