👉 In mathematics, an expansion is a mathematical process that involves breaking down a large number or expression into smaller parts. This operation can be applied to any kind of mathematical expression, from algebraic expressions to transcendental functions like trigonometric and exponential functions. For example, consider the following expression: ``` 2x^3 + 3x^2 - x ``` In this case, we are looking for a way to expand it into smaller parts. To do so, we would typically
