Answer:
There is exactly one more real solution or there is exactly one more complex solution 
Step-by-step explanation:
A quadratic equation is a polynomial of degree two
What this means is that a polynomial has two answers.
Now, from the question, we have an answer already which is a real root
Then the other answer which we do not have can take the form of two answers 
It can either be a complex root or other wise be a real root 
So the answer to this question is that ;
There is exactly one more real solution or there is exactly one more complex solution
