It has one real solution.

The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.

it has one real solution

If the discriminant of a quadratic equation is less than zero then it has no solutions.

Yes and they will be of equal value

General form of a quadratic equation is: ax2+b+c = 0 The discriminant is: b2-4ac If the discriminant equals zero then there are two equal roots If the discriminant is greater than zero then there are two different roots If the discriminant is less than zero then there are no real roots

The discriminant is -167.

(-2)2-4*8*8 = -252 The discriminant is less than zero so there's no solution to the quadratic equation.

The discriminant tells you how many solutions there are to an equation The discriminant is b2-4ac For example, two solutions for a equation would mean the discriminant is positive. If it had 1 solution would mean the discriminant is zero If it had no solutions would mean that the discriminant is negative

If the discriminant of a quadratic equation is zero then it has two identical roots.

It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
