Answer:
1. x= -4
2. x= 18
3. x= -15
4. x = 6
Step-by-step explanation:
Use relationship of angles to create equations and solve for x
First,
We are dealing with parabola since the equation has a form of,

Here the vertex of an up - down facing parabola has a form of,

The parameters we have are,

Plug them in vertex formula,

Plug in the
into the equation,

We now got a point parabola vertex with coordinates,

From here we emerge two rules:
- If
then vertex is max value - If
then vertex is min value
So our vertex is minimum value since,

Hope this helps.
