👉 In mathematics, the term "expandedness" is used to describe the process of expanding a mathematical expression or formula. It involves changing the variable in an expression so that it has a higher degree of precision and accuracy compared to its original form. For example, consider the equation: \[x^2 + 5x - 6\] If we expand this equation by introducing a new variable \(y = x^2 + 5x - 6\), we can see that the coefficient
