Let α\alphaα(a) and β\betaβ(a) be the roots of the equation (1+a3−1)x2+(1+a−1)x+(1+a6−1)=0(\sqrt[3]{1 + a} - 1){x^2} + (\sqrt {1 + a} - 1)x + (\sqrt[6]{1 + a} - 1) = 0(31+a​−1)x2+(1+a​−1)x+(61+a​−1)=0 where a>−1a \gt - 1a>−1. Then lim⁡a→0+α(a)\mathop {\lim }\limits_{a \to {0^ + }} \alpha (a)a→0+lim​α(a) and lim⁡a→0+β(a)\mathop {\lim }\limits_{a \to {0^ + }} \beta (a)a→0+lim​β(a) are
