You would need to facto 2x² + 9x - 35 to get (2x - 5)(x + 7).
We can find this first by dividing the 2x² into 2x and x, which we can put into the brackets:
(2x _ _)(x _ _)
Then we need to find two factors of -35 that have a difference of 9 when one is multiplied by 2, which gives us +7 and -5 as (7 × 2) - 5 = 14 - 5 = 9.
This gives our final answer as:
(2x - 5)(x + 7)
We cannot use foil on this expression as there are no brackets to expand.
I hope this helps!

Answer:
- 5-hour: 0.5277
- 1-hour: 0.8800
Step-by-step explanation:
The decay factor for time t can be written as ...
0.2785^(t/10)
Then the 5-hour decay factor is ...
0.2785^(5/10) ≈ 0.5277
and the 1-hour decay factor is ...
0.2785^(1/10) ≈ 0.8800
Answer: 255
