Answer:

The vertex is the point (-6,-34)

Explanation:

we know that

The equation of a vertical parabola into vertex form is equal to


y=a(x-h)^(2)+k

where

(h,k) is the vertex of the parabola

In this problem we have


y=x^(2)+12x+2

Convert in vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation


y-2=x^(2)+12x

Complete the square . Remember to balance the equation by adding the same constants to each side.


y-2+36=x^(2)+12x+36


y+34=x^(2)+12x+36

Rewrite as perfect squares


y+34=(x+6)^(2)


y=(x+6)^(2)-34

The vertex is the point (-6,-34)
