Question

The question is in the image attached. How do I show that the left side equals the right side with steps?

### Problem Statement:

2. Show that

#### (a) 

\[
\sum_{k=2}^{\infty} c_k + A \sum_{k=0}^{\infty} a_k = A(a_0 + a_1) + \sum_{k=2}^{\infty} (c_k + A a_k)
\]

**Explanation:**

This mathematical expression involves two infinite series and demonstrates a specific relationship between them. The goal is to show the equivalence between the left-hand side (LHS) and the right-hand side (RHS) of the equation.

- **Left-Hand Side (LHS):**
  - \(\sum_{k=2}^{\infty} c_k\) represents the sum of all \(c_k\) terms starting from \(k=2\) to infinity.
  - \(A \sum_{k=0}^{\infty} a_k\) denotes a scalar multiplication of \(A\) with the infinite series of \(a_k\) terms starting from \(k=0\).

- **Right-Hand Side (RHS):**
  - \(A(a_0 + a_1)\) shows the multiplication of \(A\) with the sum of the specific terms \(a_0\) and \(a_1\).
  - \(\sum_{k=2}^{\infty} (c_k + A a_k)\) combines the series of \(c_k\) and \(A a_k\) terms starting from \(k=2\). 

The task is to manipulate or reform the series on the LHS to demonstrate its equivalence with the RHS expression.
