Explanation:

remember, the standard form of a quadratic equation is

y = ax² + bx + c, with a <> 0.

a quadratic solution has always 2 zero solutions (even if they are the same, they count s actually 2 solutions).

1. 2

2. a

3. d. 2x² = -5x + 7 -> 0 = -2x² - 5x + 7

4. none. they are all quadratic equations. it does not matter on what side the squared term is. they all have a highest variable exponent 2. the squared term can't be eliminated by transforming.

5. c
