1/2 (y+4)=(x-7)^2 in vertex form step by step

is vertex form of equation

Solution:

Need to determine vertex form of the following equation  

Generic Vertex form of a quadratic equitation is as follows

So what we have to do is first make coefficient of y = 1 in our equation.

Now on Left hand side keep only y and move all the remaining term to right hand side

On comparing equation (1) with generic vertex form equation we can say that    In our case a = 2, h = 7 and k = -4

Hence is vertex form of equation

your answer would be 12
