The roots of the equation are 3 + 8i and 3 - 8i.

What is the value of c?

x2 - 6x + c = 0

c = [1]

Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;

taking x=3+8i and substituting it in our equation we get:

(3+8i) ^2-6 (3+8i) + c=0

-55+48i-18-48i+c=0

collecting the like terms we get:

-55-18+48i-48i+c=0

-73+c=0

c=73

the answer is c=73
