for the quadratic polynomial f(x) = 4x2-8ax+a, the statements which hold good is/are(multiple correct answers)
give explaination
a.) there is only one integral 'a' for which f(x) is non-negative for all x belongs to R
b.) for a< 0, the number lies between the zeroes of the polynomial
c.) f(x) =0 has two distinct solutions in (0,1) for 'a' belonging to (1/7,4/7)
d.) the minimum value of f(x) for minimum value of 'a' for which f(x) is non-negative for all x in R is zero
