Find the zeroes of the quadratic polynomial 9 t2-6t + 1 and then find the sum and product of the zeroes
zero1= 1/3 , zero2=1/3, so sum = (1/3) + (1/3) and product = (1/3) x (1/3)
zero1= 1/3 , zero2=2/3, so sum = (1/3) + (2/3) and product = (1/3) x (2/3)
zero1= 2/3 , zero2=2/3, so sum = (2/3) + (2/3) and product = (2/3) x (2/3)
