That's Correct!
It's Wrong!
To simplify the expression (-3-i)(6-i), we can use the FOIL method. First, we multiply the first terms: -3 * 6 = -18. Then, we multiply the outer terms: -3 * -i = 3i. Next, we multiply the inner terms: -i * 6 = -6i. Finally, we multiply the last terms: -i * -i = $$i^2$$ = -1. Combining all these results, we get -18 + 3i - 6i - 1. Simplifying further, we have -19 - 3i.
