Question

If the discriminant of the equation 22−+8=0 is 0, then find the value of p.

Answer 1

Answer:

Step-by-step explanation:

For a quadratic equation in the general form:  

a x 2 + b x = c = 0 the discriminant is b 2 − 4 a c The discriminant is a component of the general quadratic formula for solving a quadratic equation:

If the discriminant ( b 2 − 4 a c ) is less than zero  then the "solution" requires

the square root of a negative value which does not exist as any Real value, and therefore there can be no Real solutions to the equation.
