Write a linear factorization of the function.

f (x) = x4 + 9x2

f (x) = x2 (x + 3i) (x - 3i)

f (x) = x2 (x + 3i) 2

f (x) = x2 (3x + i) (3x - i)

f (x) = x2 (3x + i)

F (x) = x^4 + 9x^2 = x^2 (x^2 + 9) = x^2 (x^2 - (-9)) = x^2 (x - sqrt (-9)) (x + sqrt (-9)) = x^2 (x + 3i) (x - 3i)

Write a linear factorization of the function.f (x) = x4 + 9x2f (x) = x2 (x + 3i) (x - 3i)f (x) = x2 (x + 3i) 2f (x) = x2 (3x + i) (3x - i)f (x) = x2 (3x + i)
