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

nope.
unless you count (129600x^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 = (129600x^2)/2x^2
2x^2 = 129600  x^2
3x^2 = 129600
x^2 = 43200
x = ±120√3
