Answer 2

`16`

Explanation:

The discriminant of a quadratic in standard form
`ax^2+bx+c` is given by
`b^2-4ac`.

The quadratic
`-3=-x^2+2x` in standard form is
`-x^2+2x+3`. Thus, we can assign the following values:

• 
  `a` of -1
• 
  `b` of 2
• 
  `c` of 3

Therefore, the discriminant of this quadratic is
`2^2-4(-1)(3)=4+12=\boxed{16}`
