What is the discriminant of the given equation? x^2-x+2=0

-7

Step-by-step explanation:

The equation is in the form

ax^2 +bx +c =0

x^2 -x+2=0

a=1  b=-1 c =2

The discriminant is

b^2-4ac

(-1)^2-4(1)(2)

1-8

-7

For this case we must find the discriminant of the following quadratic equation:

Its roots will be given by:

Where:

By definition, the discriminant is given by:

The discriminant is -7
