Find the product. Assume all variable exponents represent whole numbers.
-$$( x - 4 ) \left( x ^ { 2 } + 4 x + 16 \right)$$
A) $x ^ { 3 } - 64$
B) $x ^ { 3 } + 64$
C) $x ^ { 3 } + 8 x ^ { 2 } + 8 x - 64$
D) $x ^ { 3 } - 8 x ^ { 2 } - 8 x - 64$

Using the FOIL method, we get:$$(x - 4)(x^2 + 4x + 16) = x^3 + 4x^2 + 16x - 4x^2 - 16x - 64 = x^3 - 64$$

Find the Product (x−4)(x2+4x+16)( x - 4 ) \left( x ^ { 2 } + 4 x + 16 \right)(x−4)(x2+4x+16)

Find the Product $( x - 4 ) \left( x ^ { 2 } + 4 x + 16 \right)$
