To find: Weather the by discriminant method that quadratic equation has two unequal real solutions, a repeated real solution or no real solution.
Answer to Problem 108AYU
The equation has two unequal real solutions.
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 positive the equation will have two unequal real solution.
Therefore, the equation has two unequal real solutions.
