Answer 1

how do i factor this thingy

Answer 2

put x^2=t
t^2+3t+2=t^2+2t+t+2=?

Answer 3

can you complete it?

Answer 4

(t+1)(t+2) -> \((x^2+1)(x^2+2)\)

Answer 5

oh so \((x^2+2)(x-i)(x+i)\)
?

Answer 6

now x^2+1=x^2-(-1)=x^2-i^2

Answer 7

okokay so A and B?

Answer 8

similarly
x^2+2=x^2-(-2)
\[=x^2-(\sqrt{2} \iota)^2\]

Answer 9

A and B and D ?_?

Answer 10

\[=(x+\sqrt{2}\iota)(x-\sqrt{2}\iota)\]

Answer 11

okokay thanks o-o
