To find: Weather the by discriminant method that
Answer to Problem 105AYU
The equation will have one repeated real solution.
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 zero the equation will have on repeated real solution.
Therefore, the equation will have one repeated real solution.
