Question

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)

Answer 1

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

Answer 2

Here's a hint:
(a^2+b^2)=(a+bi)(a-bi)
hint hint.

Answer 3

(3x+i)(3x-i)

Answer 4

Nope.

Answer 5

Lemme rewrite it.
\(\Huge (x^{2})^{2}+(3x)^2\)
hinty hint.

Answer 6

i dont understand @inkyvoyd how can you get an answer i think its f(x) = x2(3x + i)(3x - i)

Answer 7

f(x) = x2(x + 3i)2 i think this @inkyvoyd

Answer 8

Well
\(\Huge (x^{2})^{2}+(3x)^2\)
\(\huge\text{a=}x^2\text{b=}3x\)

Answer 9

\(\Huge a^2+b^2=(a+bi)(a-bi)\)

Answer 10

f(x) = x2(x + 3i)(x - 3i) ohhhhhhhhhhh @inkyvoyd lol

Answer 11

Yup.
