##### 2 Answers

The method is called completing the square

#### Explanation:

We have

in the form

where

So we divide the

so

So that is,

From this,

Line of symmetry is equal to

Find vertex of

Ans: (-3, -11)

#### Explanation:

x-coordinate of vertex:

y-coordinate of vertex:

y = y(-3) = 9 - 18 - 2 = - 11

Vertex (-3, -11)

graph{x^2 + 6x - 2 [-40, 40, -20, 20]}
