I don't know for sure I'm going to ace grade next year but I know that you you need to put the coefficients with the same variable together and the variable next to the coefficients and multiply or add or divide or subtract them and you get your answer and this is just 7th grade math I'm relying on

Answer:
The equation of the quadratic in standard form is:

Step-by-step explanation:
Since they give us the information about where the vertex of the parabola is located, and one extra points where it passes through, we can use the general form of a quadratic in vertex form:

where
is the location of the vertex (in our case the point (-2,6).
Therefore the equation above becomes:

Now,we can use the fact that the point (-4,-2) is also a point of the graph, to find the value of the parameter
:

Then, the equation of the quadratic with such characteristics becomes:

which is the equation of the quadratic in standard form.
