It has only one unique real root. There are some mathematical advantages in considering such a situation as two coincident real roots. However, given that you have to ask this question, you are still some way off getting to that level of maths - if you ever choose to do so.

What is the answer to the equation 2x2 - 10x plus 7 equals 0?
The roots of the equation are [5 +/- sqrt(11)]/2 = 4.158 and 0.842
Use the quadratic equation y equals x2 plus 3x plus 9 Calculate the discriminant to determine the number of real roots?
The discriminant is -27 and so there are no real roots.
What is the nature of the roots of 4x2 plus 15x plus 10 equals 0?
The discriminant of the equation ... (b2-4ac) = (225-160) ... is real and positive, so the roots are real and unequal.
What are the roots of the quadratic equation x2 - 6x plus 8 equals 0?
x = 2 and x = 4
What is the solution to x2 plus 7x plus 14 equals 0?
You should be able to look at this equation, or use the discriminant and know that there are no real roots.
What are the roots of the quadratic equation x2 plus 14x plus 45 equals 0?
The roots are: x = -5 and x = -9
How do you find the sum of the roots of the equation x2 plus 5x plus 9 equals 0?
