The expression x3 - 64 can be written as (x) 3 - (4) 3. What is the factorization of x3 - 64?

a3 - b3 = (a - b) (a2 + ab + b2)

(x - 4) (x2 + 4x + 8)

(x - 4) (x2 + 4x + 16)

(x - 64) (x2 + 64x + 16)

(x - 64) (x2 + 64x + 4,096)

By factoring x^3-64 put you should get the second option as your answer

(x-4) (x^2+4x+16)

The expression x3 - 64 can be written as (x) 3 - (4) 3. What is the factorization of x3 - 64?a3 - b3 = (a - b) (a2 + ab + b2)(x - 4) (x2 + 4x + 8)(x - 4) (x2 + 4x + 16)(x - 64) (x2 + 64x + 16)(x - 64) (x2 + 64x + 4,096)
