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.
