What is the discriminant of #x^2-4x+4=0# and what does that mean?
The discriminant
3] If the discriminant is negative you'll have two complex solutions (in this case, at least for now, you stop and say that there will not be REAL solutions).

The discriminant is zero. It tells you that there are two identical real roots to the equation.
If you have a quadratic equation of the form
The solution is
The discriminant "discriminates" the nature of the roots.
There are three possibilities.
Your equation is
This tells you that there are two identical real roots.
We can see this if we solve the equation by factoring.
There are two identical real roots to the equation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
