You mean find vertex. Solving for X is another matter, using the quadratic formula here.

Vertex form:

X2 + 6X - 2 = 0

X2 + 6X = 2

Halve the linear term( 6), square it and add it to both sides

X2 + 6X + 9 = 2 + 9

factor the left side and gather terms on the right

(X + 3)2 = 11

(X + 3)2 - 11 = 0

================vertex form

(- 3, - 11 )
