Hello from MrBillDoesMath!

Choice B

Discussion:

In the original statement, x^4 - 4x^2 +4,   note x^4 is the square of x^2 suggesting that if we set u = x^2 the original equation is equivalent to

u^2  -4u + 4                    

which factors as

(u -2)^2

Since u = x^2, the final factorization is

(x^2 -2) ^2

This is Choice B

Thank you,

MrB
