Answer 2

It seems like you've provided a list of algebraic expressions. Let me address each of them individually:

1. x^2 - 16: This is a quadratic expression that can be factored as (x + 4)(x - 4).

2. 5y - 10xy: This is a linear expression in terms of y and x. You can factor out 5y from both terms: 5y(1 - 2x).

3. 49a^2 + 9b^2 + 42ab: This is a quadratic expression in terms of a and b. However, it cannot be factored into simpler terms unless you want to express it as a sum of squares: (7a)^2 + (3b)^2 + 2(7a)(3b).

4. 4x^2 - 12xy + 9y^2: This is another quadratic expression that can be factored as (2x - 3y)^2.

5. 125 - a^3: This is a difference of cubes. You can factor it as (5 - a)(25 + 5a + a^2).

If you have any specific questions or need further assistance with these expressions, please feel free to ask.
