1. 12x + 16y^2

Factor out the greatest common factor:

4(3x + 4y^2)

2. 25x^2yz - 10xz

Factor out the common factor 5xz:

5xz(5xy - 2)

3. a^2 - 9

This is a difference of squares, which can be factored as:

(a + 3)(a - 3)

4. 121 - 49x^2

This is a difference of squares:

(11 + 7x)(11 - 7x)

5. x^2 + 16x + 64

This is a perfect square trinomial:

(x + 8)^2

6. 4a^2 + 12ab + 9

This is a perfect square trinomial:

(2a + 3)^2

7. x^2 + 5x + 6

This can be factored into:

(x + 2)(x + 3)

8. x^2 - x - 20

This can be factored into:

(x - 5)(x + 4)

9. a^3 + b^3

This is a sum of cubes:

(a + b)(a^2 - ab + b^2)

10. 27x^3 - 8y^3

This is a difference of cubes:

(3x - 2y)(9x^2 + 6xy + 4y^2)

These are the completely factored forms of the given expressions.
