Question

Write a linear factorization of the function.

f(x) = x^4 + 36x^2

A. f(x) = x^2(6x + i)2

B. f(x) = x^2(x + 6i)2

C. f(x) = x^2(6x + i)(6x - i)

D. f(x) = x^2(x + 6i)(x - 6i)

Answer 1

Is it a?

Answer 2

d

Answer 3

What would you do with the 12i ?

Answer 4

12i???

Answer 5

Yea don't you get a 12i when u go backwards to get the same problem as before ?

Answer 6

i will try to solve it please correct me

Answer 7

x^4 +36x^2 = x^2(x^2 +6^2)

Answer 8

and (x^2 +6^2) does not have solution on the reals numbers so

Answer 9

x^2 +6^2= (x+6i)(x-6i)

Answer 10

so the solution is x^2(x+6i)(x-6i)

Answer 11

Ok I understand now I was looking at it in a different way :) thank u :)
