Answer: Last option.
Step-by-step explanation:
For this exercise you need to find the Discriminant.
The formula used to find the Discriminant, is the following:
In this case, given the Quadratic equation:
You can identify that:
Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.
You get that this is:
By definition, if:
Then the Quadraitc equation has 2 nonreal solutions.
