Answer:
Step-by-step explanation:
1. The coefficient of 2 is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.
This means that the answer is a = 2, b =1, c =5.
2. You can simply cancel out both 3s by dividing, which leaves us with 1±9.
3. The answer is c. Unfortunately, I can't explain that, it's just a well known formula.
I hope this helped!
