Answer 2

Answer:

$x=2\text{ or }x=-2$

Coordinates of the vertex of parabola are: (0,-8).

Step-by-step explanation:

We have been given an equation $2x^2=8$ and we are asked to find the solution of our given equation.

First of all let us divide both sides of our equation by 2.

$\frac{2x^2}{2}=\frac{8}{2}$

$x^2=4$

Upon taking square root of both sides of our equation we will get,

$x=\sqrt{4}$

$x=\pm 2$

$x=2\text{ or }x=-2$

Therefore, the solutions for our given equation are $x=2\text{ or }x=-2$.

We can see from our attachment that the vertex of our parabola is at point (0,-8).
