👉 Telescoping is a mathematical operation that involves breaking down an expression into smaller and more manageable parts. In other words, it involves rearranging or decomposing an expression into simpler forms or components. For example, consider the expression 2x^3 + 3x^2 - x - 4. If we try to simplify this expression by using the telescoping method, we can break down the expression into smaller parts: 1. First, factor out a common term: (2x
