Step-by-step explanation:
please type the question correctly, it's confusing. thanks
For this case we have the following quadratic equation:

Where:

By definition, the discriminant of a quadratic equation is given by:

We have to:
Two different real roots
Two different complex roots
Two equal real roots
Substituting the values we have:

So, we have two different complex roots
Answer:
Two different complex roots
A. Both triangles equal 50 and 10x5 is 50. Therefore, y=5.
