Question

What is the value of the discriminant for the quadratic equation 0 = x + 2 + x^2?

Discriminant = b^2— Час

Answer 1

The discriminant of the quadratic equation is -7.

Explanation:

We are given the following quadratic equation in the question:

`x^2+x+2 = 0`

Comparing to general quadratic equation:

`ax^2+bx+c = 0\\a = 1\\b = 1\\c = 2`

We have to find the discriminant of the quadratic equation.

Formula:

`d = b^2-4ac`

Putting values, we get,

`d = (1)^2 - 4(1)(2) = 1 - 8 = -7`

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