```							hello student. note that aruns answer is incomplete.correct answer is:if ax^2-2x+9=0 is a quad eqn, then discriminant is 04 – 36 a = 0a = 1/9.but if it is not a quadratic, then a= 0 in which case it becomes – 2x+9= 0 or x= 9/2, which is only a single root.so, possible values of a are 1/9 and 0.kindly approve :)
