Since 4xy2 is a factor of 20x2y4, it is automatically the GCF.
The only common factor of 10a and 5b is a 5. So the factored form will be something like: 5(2a _ b) assuming the _ is filled in with the proper operation (+ - * / etc.). If the original expression is 10a + 5b, the answer would be 5(2a + b).
It stays the same because it does not have any common terms. A: 6y-4xy
The difference of cubes has a formula. (4x - y)(16x2 + 4xy + y2)
