Question

Which of the following is the complete list of roots for the polynomial function mc025-1.jpg? –3 + 2i, –3 – 2i –2, –4 –2, –4, –3 + 2i, –3 – 2i –2, –4, –3 + 2i, 3 + 2i

Answer 1

Thank you for asking this question.  

I am writing the options separately in order to help you understand the question better.  

a. –3 + 2i, –3 – 2i

b. –2, –4

c. –2, –4, –3 + 2i, –3 – 2i

d. –2, –4, –3 + 2i, 3 + 2

Answer:

f(x) = (x² + 6x + 8) ( x² + 6x + 13)

x1 = -2  

x² = -4

x³ = -3 + 2i

x⁴ = -3 -2i

So the final answer for this question is the option C) -2, - 4, - 3 + 2 i, - 3 - 2 i
