Answer:
y = (x + 3)² - 7
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
To obtain this form use the method of completing the square
Given
y = x² + 6x + 2
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = x² + 2(3)x + 9 - 9 + 2
= (x + 3)² - 7
