1. Problem Description
The problem asks us to determine the type of solutions of the quadratic equation using the discriminant, without actually solving the equation. The possible solution types are: two rational solutions, two irrational solutions, one rational solution, or two nonreal complex solutions.
2. Solution Steps
First, we need to rewrite the given equation in the standard quadratic form .
Now, we can identify the coefficients: , , and .
The discriminant is given by the formula:
Substitute the values of , , and into the formula:
Now, let's analyze the discriminant:
- If , there are two distinct real solutions.
- If is a perfect square, the solutions are rational.
- If is not a perfect square, the solutions are irrational.
- If , there is one real solution (a repeated root), which is rational.
- If , there are two nonreal complex solutions (conjugate pairs).
In our case, . Since , the equation has two nonreal complex solutions.
3. Final Answer
Two nonreal complex solutions
