Can I simplify (12960 - 0.1x^2) / 0.2x^2 any further? How?

nope.

unless you count (129600-x^2)/2x^2 as simpler

Thank you!

How would I solve

1 = (12960 - 0.1x^2) / 0.2x^2

just as you normally would:

1 = (12960 - 0.1x^2) / 0.2x^2

1 = (129600-x^2)/2x^2

2x^2 = 129600 - x^2

3x^2 = 129600

x^2 = 43200

x = ±120√3
