Please check and see if my answer are correct
1). 24v^2w^5x^820v^7w^9= 4v^2w^5(5v^5w^46x^8)
2). 8125z^2= (5z+9)(95z)
3). 5y^37y^215y+21=(y^23)(5y7)
4). x^2+4x12= (x+6)(x2)
5). 3x^226x+16= (x8)(3x2)
6).4v^6+6v^518v^4= 2v^4(2v3)(v+3)
7). solve for y
y^2+6y+8=0 y= 2,4
8).2v^2+4v14=(v+1)^2= v=3,5
Please check these for me

all correct.
Though I'd have written #2 as (9+5z)(95z) to associate it more readily with the difference of two squares.
