The vertex form of this function.
X2 + 22X = 31
Halve the linear term ( 22 ) square it and add it to both sides.
X2 + 22X + 121 = 31 + 121
Factor the left side of this equation and gather terms on the right side.
(X + 11)2 = 152
(X + 11)2 - 152 = 0
===================vertex form of this function
(- 11, - 152 )
