Answer:
The discriminant of an equation is a value that can be used to determine the number and type of roots the equation has. In this case, the discriminant of the first equation is -108, which means that it has two imaginary roots. The discriminant of the second equation is 144, which means that it has two real roots. The discriminant of the third equation is -20, which means that it has two complex roots. The discriminant of the fourth equation is 0, which means that it has two equal roots. The discriminant of the fifth equation is 21, which means that it has three real roots.
