Answer:
No real solutions.
B is correct
Step-by-step explanation:
Given: 
We are given a quadratic equation and need to solve for x.
Quadratic formula: 

For our equation, a=3, b=1 and c=10
Substitute the value of a, b and c into formula


Here, Roots are imaginary because number inside the square root is negative.
Hence, No real solutions.
