ok sure how does it work?

Answer 8

i thought you used keep flip change on these problems.... i just was at a class for this but i could be wrong

Answer 9

Basically for x² - 25 (the answer) you need to find the factors of both, for 25 it is 5 and for x² it is X thus you get (x+5)(x-5)

Answer 10

like a number that both can be multiplied on?

Answer 11

Answer 12
