Answer :
Root of 2i also means there is a root of -2i
Root of 3i also means there is a root of -3i
Factors will be (x^2 + 4)(x^2 + 9).
Multiply this out to get the polynomial:
x^4 + 13x^2 + 36
Root of 3i also means there is a root of -3i
Factors will be (x^2 + 4)(x^2 + 9).
Multiply this out to get the polynomial:
x^4 + 13x^2 + 36
Answer:
Step-by-step explanation:
f(x) = (x + 2i)(x + 3i)(x – 2i)(x – 3i)
Choice D.
