None. This function does not cross the x axis. The "solutions" or "zeros" are imaginary.
How do you know
Because the discriminate is a negative number, and the square root of a minus number does not lend itself to anything that will cross the x axis.
a = 3
b = 9
c = 29
D = b^2 - 4ac
D = 9^2 - 4*3*29
D = 81 - 348
D = - 268
To further convince you, I have included the graph for this.
