Answer:

y = 3 ( x − 2 ) 2 − 1

Step-by-step explanation:

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.

Very glad I was able to assist you even though you're pretty rude.

Ohhh ok so im actually not sure if I’m doing this right but if I remember correctly.. there has to be a squared binomial so heres my answer:

3(x-2)^2-1 and the vertex is (2,-1)

Now im not completely sure if I’m right but basically what I did was get a squared binomial and added and multiplied to it to make it equal to the previous trinomial.

Sorry if I’m wrong. Hope this helps some.
