hat is the value of the discriminant for the quadratic equation 0 = x + 2 + x2? Discriminant = b2 – 4ac –9 –7 7 9
Dovator [93]
For the general quadratic equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.

So, for x^2 + x + 2 = 0, a = 1, b = 1, and c = 2, therefore

b^2 - 4ac = 1^2 - 4(1)(2) = 1 - 8 = - 7.
