Above are roots of equation 9x^2 - 18x + 5 = 0 and 9x^2 - 18x + 5 = 0
the discriminant of of the equations are 18^2 - 4 * 9 * 5 = 324-180 = 144
so roots are real and product of roots of 9x^2 - 18x + 5 = 0 is \frac{5}{9} and same is the product of other equation and so we get overall product \frac{25}{81}
