SOLUTION: f 5 - 3i is a root of the equation z^2 - 10z + k = 0 find the value of k?
I got something like this can you fix it and add something new?

if (5 - 3i) is a root, the
Question 1017155: f 5 - 3i is a root of the equation z^2 - 10z + k = 0 find the value of k?
I got something like this can you fix it and add something new? if (5 - 3i) is a root, then (5 + 3i) is a root, too (complex conjugates)...
*
* product of the roots = c / a
*
* (5 + 3i)(5 - 3i) = 25 - 9iČ = 34
*
* k = 34
