Answer:

The discriminant of the quadratic equation is -7.

Step-by-step explanation:

We are given the following quadratic equation in the question:

[tex]x^2+x+2 = 0[/tex]

Comparing to general quadratic equation:

[tex]ax^2+bx+c = 0\\a = 1\\b = 1\\c = 2[/tex]

We have to find the discriminant of the quadratic equation.

Formula:

[tex]d = b^2-4ac[/tex]

Putting values, we get,

[tex]d = (1)^2 - 4(1)(2) = 1 - 8 = -7[/tex]

Thus, the discriminant of the quadratic equation is -7.
