Question
The characteristic quadratic polynomial of homogeneous second-order recurrence relation with constant coefficients recurrence relation is
Solution
The characteristic quadratic polynomial of a homogeneous second-order recurrence relation with constant coefficients is given by:
ax² + bx + c = 0
Here, a, b, and c are constants and x is the variable. This polynomial is derived from the recurrence relation:
a_n = αa_(n-1) + βa_(n-2)
By assuming a solution of the form a_n = r^n and substituting this into the recurrence relation, we get the characteristic equation:
r² - αr - β = 0
This is a quadratic equation in r, and its roots give the solutions to the recurrence relation. The coefficients of r², r, and the constant term in this equation correspond to a, b, and c in the characteristic polynomial.
