Write the general form of a linear homogeneous recurrence relation of degree 2.
Think about how each term relates to the previous ones.
What is meant by characteristic roots?
Reflect on where they come from.
What form does a linear homogeneous recurrence equation typically take?
Look for how previous terms in the sequence appear.
True or False: The characteristic roots of a recurrence equation can be the same.
Consider the nature of quadratic equations.
For T(n) = 4T(n-1) - 4T(n-2), derive the characteristic equation and roots. Then find a general solution.
Follow the steps to construct your polynomial from the recurrence relation.
Given the initial conditions T(0)=2, T(1)=3, find specific constants A and B for T(n) = A * 3^n + B * 1^n.
