Answer: Choice C
Vertex = (5, -2)
===============================================
Explanation:
Vertex form is
where the vertex itself is located at (h,k)
As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.
In the case of choice C, we have
which is the same as
and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)
I don't know if i'm right or what because I haven't learned binomial in like almost 4 years. (3x+y)?
Wouldn’t the answer be 19.
6x^2 is the correct answer to the problem.
