What is the discriminant d of the equation? n^2+2n−2=0

the discriminant of the given equation is, 12

Step-by-step explanation:

A quadratic equation  ....[1] then

Discriminant of the quadratic equation is given by:

where D is the discriminant of the quadratic equation

Given the equation:

On comparing with equation [1] we have;

a = 1, b = 2 and c = -2

Then using formula for discriminant, we have;

⇒

⇒

Therefore, the discriminant of the given equation is, 12
