Answer:
x² - 6x + 9

Explanation:
Before we begin, remember the following:
(a - b)(a - b) = (a - b)² = a² - 2ab + b²

Now, for the given, we have:
(x - 3)(x - 3)
We can note that the two brackets are identical. Therefore, we will simply apply the above rule as follows:
(x - 3)(x - 3)
(x - 3)² = (x)² - 2(x)(3) + (3)²
           = x² - 6x + 9

Hope this helps :)

9966 [12]

Answer:

y = x² + 8x - 3

y = x² + 2(x)(4) + 4² - 4² - 3

y = (x + 4)² - 16 - 3

y = (x + 4)² - 19

Vertex: (-4,-19)
