Factor:
64a%5E3c%5E6+%2B+x%5E6y%5E9 As you can see, the two terms have no common factors so this expression is not factorable!
A second look shows that the first term is a cube %284ac%5E2%29%5E3 but the second term is not! If the exponent of the y had been 8 or 27, then the expression woul have been factorable as the sum of two cubes.
