most of them 4,7,8,9,11,12,13,14,15,16,1718,19,20,21,22,24 All these # can be factored better.Don't forget that variables can be factored too. Example # 19 25x^3- 15x^2 =5x^2(5x-3) Also you want the largest common factor. Example #24 8g^2+16g-8 = 8(g^2+2g-1) Hope this helped.

everything is good except for #13, the answer should be 4(c^3 - 2c^2 + 2)

11t- sixteen=36 +sixteen=+sixteen 11t =fifty two /11 /11 t =4.727 it could no longer look precise, yet once you double examine by using inputing 4.seventy two for x and it incredibly is 36. You dont subtract sixteen on the commencing up, you upload it.

3) A lot of these need to be factored further.
x(x+6)
Similarly # 4,11,12,18,19,20,21,22,24
