1) one of the factors is x+3
2) k^(x+3)
3) 88a^2-a-35
=(11a-7)(8a+5)
2) k^(x+3)
3) 88a^2-a-35
=(11a-7)(8a+5)

1) common factor can be 2 or (x+3)
2) k=x+3
3) don't know, i have to think a moment, wait me!

3) ans: (11a-7)(8a+5)
proof: (11a-7)(8a+5)
= 88a^2+55a-56a-35
=88a^2-a-35
2) k=x+3
3) don't know, i have to think a moment, wait me!
