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

1.	If α,β are the roots of the equation ax2+bx+c=0 and Sn=αn+βn then aSn+1+bSn+cSn−1=(n≥2)
Answer» If $α, β$ are the roots of the equation $a x^{2} + b x + c = 0 a n d S_{n} = α^{n} + β^{n} t h e n a S_{n + 1} + b S_{n} + c S_{n - 1} = (n \geq 2)$
