maybe i should have put this under Algebra or just math..I have no clue.
x = [1 +/-sqrt(-19)]/2
= 0.5 +/- 2.17945 i
Both roots are complex.
= 0.5 +/- 2.17945 i
Both roots are complex.
So this would be written out as:
1+√19/2 and 1-√19/2
is that correct
1+√19/2 and 1-√19/2
is that correct
Get to know the "quadratic formula" for problems like this. The formula is at

(You can also plug in coefficients and get answers directly there).
It should be also in your textbook.
