Mathematics · Difference Equations
A difference equation is given as x(k + 2) + 3x(k + 1) + 2x(k) = 0 with initial conditions x(0) = 0 and x(1) = 1. The solution of this equation is:
- 1x(k) = (-1) k + (2) k
- 2x(k) = (-1) k - (2) k
- 3x(k) = (-1) k + (-2) k
- 4x(k) = (-1) k - (-2) k✓
Correct answer
x(k) = (-1) k - (-2) k
