If the discriminant is zero in a quadratic formula, determine the number of real solutions for that quadratic formula. .

The discriminant gives the type of solutions that will be found for a

quadratic equation.

The number of real solutions for the quadratic formula is one.

Reasons:

If the discriminant in the quadratic formula, y = a·x² + b·x + c, is the value;

Where;

a, b, and c are real numbers, we have

A zero discriminant gives;

Therefore;

is one real number

Therefore;

The number of real solutions for the quadratic formula is one.

we know that

The formula to calculate the solutions of the quadratic equation of the form is equal to

where

The discriminant of the quadratic equation  is equal to

in this problem we have  that

so

substitute in the formula

 -------> is one real solution

therefore

The answer is

one real solution

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
