If roots of `x^2-(a-3)x+a=0` are such that at least one of them is greater than 2, then `a in [7,9]` b. `a in [7,oo]` c. `a in [9,oo]` d. `a in [7,9]`

If the roots of 9x^(2) - 2x +7 = 0 are 2 more than the roots of ax^(2) + bx + c = 0 , then 4a - 2b + c can be

If both the roots of the equation x^(2)-9x+a=0 are positive and one is greater than 3 and other is less than 3, then all possible values of a is-
