A) $6 x ^ { 24 }$
B) $- 64 x ^ { 8 }$

The expression can be simplified by combining like terms, which are terms that have the same variable raised to the same power. Here, all terms are like terms because they all have $x^8$. Adding and subtracting the coefficients gives $2 + 8 - 4 = 6$, resulting in $6x^8$.
