The expression "4n^2 + 25" is called a quadratic expression because it includes a term with the variable raised to the second power (n^2). In this case, it is a specific type of quadratic expression known as a sum of squares, as it can be expressed in the form of (a^2 + b^2) where (a = 2n) and (b = 5).
