factor the polynomial function over the complex numbers. f(x) = x^4 + 3x^2 - 4? WILL GIVE BRAINLIEST AND 50 POINTS (ALGEBRA 2) NEED ANSWER ASAP

(x+1)(x−1)(x+2i)(x−2i)

Step-by-step explanation:

I saw this on my assignment, study guide, and test. It was correct and checked by my teacher.

(x+1)(x−1)(x+2i)(x−2i)

Step-by-step explanation:

look a the sides they are perpendicular

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
