If α and β are the roots of the quadratic equation ax2+bx+c=0, then – InterviewSolution

1.	If α and β are the roots of the quadratic equation ax2+bx+c=0, then limx → α1−cos(ax2+bx+c)(x−α)2 is :
Answer» If $α$ and $β$ are the roots of the quadratic equation $a x^{2} + b x + c = 0,$ then $lim x \to α \frac{1 - cos (a x^{2} + b x + c)}{(x - α)^{2}}$ is :
