Answer:
Option 3rd is correct
The equation has no real number solutions because the discriminant is less than 0
Step-by-step explanation:
Discriminant(D)of a quadratic equation is given by:
- If D = 0 , real zero of multiplicity 2.
- If D < 0, two zeros that are complex
- if D > 0, then two real zeros that are distinct.
As per the statement:
Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation:
On comparing the given equation with we have;
a = 1, b = 4 and c = 8
then;
⇒
By definition;
Discriminant is less than 0
equation does not have real roots
Therefore, the equation has no real number solutions because the discriminant is less than 0
