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)
