Question

What is the value of the discriminant for the quadratic equation 0 = x + 2 + x2?

Discriminant = b2 – 4ac

–9
–7
7
9

Answer 1

In the given quadratic equation 0 = x^2 + x + 2, we have:
a = 1
b = 1
c = 2

Now, we can calculate the discriminant:
Discriminant = b^2 - 4ac
Discriminant = 1^2 - 4*1*2
Discriminant = 1 - 8
Discriminant = -7

Therefore, the value of the discriminant for the quadratic equation 0 = x^2 + x + 2 is -7.
