If for all real values of `a`, one zero of the polynomial x^2-3ax+f(a) is double of the other zero then find f(x).

Question

Vikas TU · Answer

Dear Student,

let one root be m , then the other root must be 2m.

Sum of roots = 3m = 3a

 M= a

Product of roots = 2m^2 = 2a^2 = f(a)

 F(x)= 2x^2

Cheers!!
