D. All three methods would be

(The answer choices are the same for all the problems)

Answer 1

1. C

2. A

3. C

Explanation:

1. The equation is most easily solved through the quadratic formula since it’s a term is greater than 1.

2. The equation is most easily factored since it’s a term is 1.

3. The equation is most easily solved by the quadratic formula since it’s a term is greater than 1.
