Just an addendum, though the answer by @Vladimir Sovkov is correct.
Using round to convert those results is wrong. Instead use either double or vpa to do so, depending on whether you want a symbolic or double precision answer. Thus we see:
digits 20
>> vpa(solv)

0.019818975623042097611
- 12.0 - 12.019818975623042098i
- 12.0 + 12.019818975623042098i
- 22.40946858177980274 + 6.0099094878115210488i

- 22.40946858177980274 - 6.0099094878115210488i
- 1.5905314182201972597 + 6.0099094878115210488i
- 5.9900905121884789512 - 10.40946858177980274i
- 18.009909487811521049 + 10.40946858177980274i
- 18.009909487811521049 - 10.40946858177980274i
- 5.9900905121884789512 + 10.40946858177980274i
The second solution is apparently the one you wanted, as has already been shown.
