Application +4 | -1

\alpha, \beta

are the roots of the equation

a x^2+b x+c=0

and

A_n=\alpha^n+\beta^n

, then

a A_{n+2}+b A_{n+1}+c A_n

is equal to

View answer and explanation

Correct option: A

Option A (0) is correct because the expression

a A_{n+2}+b A_{n+1}+c A_n

simplifies to 0 using the properties of roots of a quadratic equation.
