Answer 1

I can't match them because none of the four given expressions are equivalent to any of the others. Here are each one’s equivalent forms so you can see:

- y = x^2 + 2x − 8
- factored: (x + 4)(x − 2)
- vertex form: (x + 1)^2 − 9

- y = (x + 9)(x + 1)
- expanded: x^2 + 10x + 9
- vertex form: (x + 5)^2 − 16

- y = (x + 3)^2 − 8
- expanded: x^2 + 6x + 1

- y = x^2 − 10x + 16
- factored: (x − 2)(x − 8)
- vertex form: (x − 5)^2 − 9

If you can paste the left-column and right-column items separately (or the intended set of responses to drag into each blank), I’ll match them correctly.
