Answer:
1st option
Step-by-step explanation:
Here we are trying to prove that not all fractions are less than 1. So we have to choose an example in which the fraction is more than 1.
1) 
This fraction is greater than 1 hence it can prove that the conjecture is false.
2) ½ is lesser than 1 and will not prove that the conjecture is false.
Answer:
-2
Step-by-step explanation:
I think this was the question you were talking about.
8x2+6x-2
I think! because 8,6, and 2 are all divisible by 2
and 3. Factor the quadratic
2(4x-1)(x+1)
