Answer:
If
or
, there is only one solution to the given quadratic equation.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:

This polynomial has roots
such that
, given by the following formulas:



The signal of
determines how many real roots an equation has:
: Two real and different solutions
: One real solution
: No real solutions
In this problem, we have the following second order polynomial:
.
This means that 
It has one solution if




We can simplify by 8

The solution is:
or 
So, if
or
, there is only one solution to the given quadratic equation.
