Using the results of Exercises 101104, make a conjecture about another nonreal complex solution of the equation

Question:

Using the results of Exercises 101–104, make a conjecture about another nonreal complex solution of the equation x2 - 6x + 13 = 0, and verify it.



Data from in Exercises 101


Show that 1 + 5i is a solution of x2 - 2x + 26 = 0.



Exercises 102


Show that 1 - 5i is a solution of x2 - 2x + 26 = 0.



Exercises 103


From Exercises 101 and 102, the nonreal complex solutions of the equation


image


are 1 + 5i and 1 - 5i. What do we call two complex numbers a + bi and a - bi?



Exercises 104


Show that 3 + 2i is a solution of the equation x2 - 6x + 13 = 0.
