## Homework Statement

Identify the vertex and x-intercept(s) of the quadratic function algebraically.

## Homework Equations

f(x) = 1/2x^2 - 4

1/2 Is the coefficent if its not clear.

## The Attempt at a Solution

Ok I do not need help finding the vertex I have already got that, I need help factoring it out to find the x-intercepts.

Here is my attempt

0 = 1/2x^2 - 4

0 = 1/2 (x^2 - 8)

That is as far as I can factor it, I am terrible at factoring these and I actually have a way easier time factoring trinomials and polynomials.

Could you please explain how I am to factor farther and how am I supposed to solve for the x-intercepts after its all factored. I have even looked all over the internet for a good factoring tutorial guide but I just cannot even understand them.

Thanks
