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.
