Consider the equation $x^2 + \alpha x + \beta = 0$ having roots $\alpha, \beta$ such that $\alpha \neq \beta$. Also consider the inequality $||y - \beta| - \alpha| < \alpha$,then:

  • A
    The inequality is satisfied by exactly two integral values of $y$.
  • B
    The inequality is satisfied by all values of $y \in (-4, 2)$.
  • C
    The roots of the equation are of the same sign.
  • D
    $x^2 + \alpha x + \beta > 0$ for all $x \in [-1, 0]$.
