It appears that some parts of the text were misinterpreted during extraction, likely due to the quality of the image. Let me manually interpret and factor the correct equations from the provided image.

Correctly Interpreted Equations for Factoring:

1. $y^3 + 9y^2$
2. $5x^2 y^3 + 15x^3 y^2$
3. $12t^5 - 20t^4 + 8t^2 - 16$
4. $p^2 - 36$
5. $25 - x^2$
6. $4a^3 - 49a$
7. $(a + b)^2 - 100$
8. $9 - (x - y)^2$
9. $y^3 + 8$
10. $64y^4 + y$

Let’s go ahead and factor them step by step.

Solutions:

1. Factor $y^3 + 9y^2$: $y^3 + 9y^2 = y^2(y + 9)$

2. Factor $5x^2 y^3 + 15x^3 y^2$: $5x^2 y^3 + 15x^3 y^2 = 5x^2 y^2 (y + 3x)$

3. Factor $12t^5 - 20t^4 + 8t^2 - 16$: Group terms and factor by grouping: $12t^5 - 20t^4 + 8t^2 - 16 = 4t^2(3t^3 - 5t^2 + 2) - 16$ At this point, no further factoring is possible.

4. Factor $p^2 - 36$: This is a difference of squares: $p^2 - 36 = (p - 6)(p + 6)$

5. Factor $25 - x^2$: This is also a difference of squares: $25 - x^2 = (5 - x)(5 + x)$

6. Factor $4a^3 - 49a$: Factor out $a$: $4a^3 - 49a = a(4a^2 - 49) = a(2a - 7)(2a + 7)$ (Difference of squares)

7. Factor $(a + b)^2 - 100$: This is a difference of squares: [ (a + b)^2 - 100 = [(a + b) - 10][(a + b) + 10] ]

8. Factor $9 - (x - y)^2$: This is a difference of squares: $9 - (x - y)^2 = (3 - (x - y))(3 + (x - y)) = (3 - x + y)(3 + x - y)$

9. Factor $y^3 + 8$: This is a sum of cubes: $y^3 + 8 = (y + 2)(y^2 - 2y + 4)$

10. Factor $64y^4 + y$: Factor out $y$: $64y^4 + y = y(64y^3 + 1)$
