Assume That the Characteristic Equation for a Homogeneous Linear Recurrence

Short Answer

Assume that the characteristic equation for a homogeneous linear recurrence relation with constant coefficients $$\text { is } ( r - 3 ) ^ { 2 } ( r - 4 ) ^ { 3 } ( r + 7 ) ^ { 2 } = 0 \text {. Describe the form for the general solution to the recurrence relation. }$$
