What would this be??​

The area would be 15.75 feet squared!

(4+5/2)(3.5) = 15.75

This equation has the next form:

To find if the equation has two complex solutions we have to check if the discriminant is negative, as follows:

Then, the first case has two complex solutions.

In the second case,

The discriminant in this case is:

Then, the second case has two complex solutions.

In the third case,

The discriminant in this case is:

Then, the third case has two real solutions.

In the fourth case,

The discriminant in this case is:

Then, the fourth case has two complex solutions.
