To determine the number of real solutions of
Explanation of Solution
There may be two real solutions of the quadratic equation. There may be two equal real solutions and there may be zero real solutions of equation.
Solutions of the equation depend on the discriminant of the equation.
Discriminant of a standard equation
If discriminant is less than zero equation have no real solution.
If discriminant is greater than zero equation have two real solutions.
If it is equal to zero than there is two equal real solutions.
Example of two real solution is,
Example of no real solution is,
