Vertex form of equation is $y= 2(x+3)^2-30$

$y= 2x^2+12x-12 or y= 2(x^2+6x)-12$ or

$y= 2(x^2+6x+9)-18-12$ or

$y= 2(x+3)^2-30$ , comparing with vertex form of

equation $y= a(x-h)^2+k ; (h,k)$ being vertex we get here

$h= -3 .k=-30 :.$ Vertex is at $(-3,-30)$ and vertex

form of equation is $y= 2(x+3)^2-30$ [Ans]

What is the vertex form of y=2x^2+12x-12y=2x^2+12x-12?
