Answer:
constant = -12
Step-by-step explanation:
Let the given equation be
2x² + 8x - 12 = 0 --------(1)
Here B² =(2√2)^2 = 8
Add 8 in both sides of (1)
Step1 : 2x² + 8x + 4 = 12 + 4
Step 2: x² + 4x + 4 = 16
step 3 : x² + 4x + 4 - 16 = 0
Step 4: x² + 4x - 12 = 0 ---(4)
From the (4) we get constant = -12

Step-by-step explanation:
The correct domain is [3,8].
Given:
Monthly fees for the local pool are $8 per month and $2 per visit.
Hector pays $34 in pool fees total for the month.
To find:
The number of times he visit the pool.
Solution:
We have,
Monthly fee of pool = $8
Additional fee = $2 per visit
Let Hector visit x times.
Additional fee for x times = $2x
Total fee = Monthly fee + Additional fee



Divide both sides by 2.


Therefore, Hector visit the pool 13 times.
