anonymous · Answer

please help!! last question!! just need the answer.. pleaseeeee!!

anonymous · Answer

all combinations of all factors of 18 over all factors of 2

anonymous · Answer

18: 1,2,6,9,18
2:1,2
1,-1,2,-2,3,-3,6,-6,9,-9,18,-18,(9/2),(-9/2)

anonymous · Answer

so thats the answer ?^^

anonymous · Answer

hmm... if you don't recognize the answer... maybe you don't understand the question.
What do YOU think you should do with the rational zero theorem?

anonymous · Answer

tbh i have no idea

anonymous · Answer

thank you for being honest
you take all of the factors of the last number divided by all of the factors of the first coeffecient, in every possible way... both positive and negative.
So, yes... the last list of numbers in my answer above should be "the answer"

ohhhhh .. ok let me see if i get the same things .
