Answer:

[tex]16[/tex]

Step-by-step explanation:

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

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

  • [tex]a[/tex] of -1
  • [tex]b[/tex] of 2
  • [tex]c[/tex] of 3

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