Hi ExtraordinaryMelon4228,

Before starting the resolution, we need to understand the different form of quadratic functions. The general form is this one:

$$f(x)=ax^2+bx+c$$

In this problem, we want the standard form, which is this one:

$$f(x)=a(x-h)^2+k$$

To go from the general form to the standard form, we need to use this formula: We then have the values of h and k, we can now write the function in the standard form. You can also use the completing square technique, it's just a bit longer to do.

I hope that helps and feel free to write us again!
