To find: Weather the by discriminant method that
Answer to Problem 103AYU
The equation has no real roots.
Explanation of Solution
Given information:
The quadratic equation is
Calculation:
The discriminant of a quadratic equation
If the discriminant is positive the equation will have two real solutions.
If discriminate is zero the equation have one repeated real solution.
If discriminant is negative then the equation has no real solution.
Consider the expression
Here,
Calculate discriminant.
Since the discriminant is negative the equation will have no real solution.
Therefore, the equations have no real solution.
