Write a linear factorization of the function. f(x) = x^4 + 4x^2
Accepted Solution
A:
We can factor x^2 from both terms:[tex]x^2(x^2+4)[/tex]This is a complete factorization over the reals, we can't go any deeper. If you're allowed to use complex numbers, we can continue to factor the parenthesis:[tex]x^2(x^2+4)=x^2(x+2i)(x-2i)[/tex]
