Answer:

Step-by-step explanation:
If the ellipse has its x-intercepts at points (2, 0) and (-2, 0) and y-intercepts at points (0, 4) and (0, -4), then its symmetric across the y-axis and across the x-axis.
Moreover,

The equation of such ellipse is

Hence, the equation of the ellipse is

Answer:
q = 4
Step-by-step explanation:
this is your equation
8 + q = 12
rearrange to find q
q = 12 - 8
q = 4
all of them is not a quadratic equations
