Does there exist a quadratic equation whose coefficients are all distinct irrationals but both the roots are rationals? Why?

  • A
    Yes,because the discriminant is a perfect square.
  • B
    No,it is impossible for irrational coefficients to yield rational roots.
  • C
    Yes,for example,$\sqrt{3}x^2 - 7\sqrt{3}x + 12\sqrt{3} = 0$.
  • D
    Yes,but only if the leading coefficient is $1$.
