Question

f(x) = x4 + 4x2

Answer 1

Write a linear factorization of the function.

Answer 2

\[f(x)=4x(1+x)\]

Answer 3

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

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

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

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

Answer 4

which one of these is it cuz i cant figure it out

Answer 5

oh wait, is the problem:
\[f(x)=x^4+4x^2\]

Answer 6

yes

Answer 7

AH HA!! Ok...
Factor out the x^2 and then it is the sum of two squares in the imaginary plane.
\[f(x)=x^2(x+2i)(x-2i)\]
...messy.
