Answer:

[tex]-2^{2} -4(1)(5)[/tex]

so the answer would be c.

Step-by-step explanation:

The discriminant is the following equation:

[tex]b^{2} -4ac[/tex]

You just simply plug in the values of the coefficients.

[tex]0=x^{2} -2x+5[/tex]

a = 1 (first terms coefficient)

b = -2 (second terms coefficient)

c = 5 (last terms coefficient)
