Use the discriminant, LaTeX:  \displaystyle b^2-4ac to determine the number and type of solutions to the equation LaTeX:  \displaystyle 9 x^{2} - 2 x + 1 = 0 . No points will be given if the discriminant is not used.

Since the discriminant is LaTeX:  \displaystyle b^2-4ac=(-2)^2-4(9)(1)=-32 and is negative, the equation has two imaginary solutions.
