Answer 2

To find the discriminant of the quadratic equation $x^2 + x + 3 = 0$, we can use the formula for the discriminant, which is given by $b^2 - 4ac$ in the quadratic equation $ax^2 + bx + c = 0$.

In the equation $x^2 + x + 3 = 0$, we can identify $a = 1$, $b = 1$, and $c = 3$.

Now, plug these values into the formula for the discriminant:

$$\text{Discriminant} = b^2 - 4ac$$

$$= (1)^2 - 4(1)(3)$$

$$= 1 - 12$$

$$= -11$$

So, the discriminant of the quadratic equation $x^2 + x + 3 = 0$ is -11.
