Quadratic Equation And Inequalities

Let \(\alpha\)(a) and \(\beta\)(a) be the roots of the equation \((\root 3 \of {1 + a} - 1){x^2} + (\sqrt {1 + a} - 1)x + (\root 6 \of {1 + a} - 1) = 0\) where \(a > - 1\). Then \(\mathop {\lim }\limits_{a \to {0^ + }} \alpha (a)\) and \(\mathop {\lim }\limits_{a \to {0^ + }} \beta (a)\) are
