Input (English): Galois theory can be applied to the symmetric type of these expressions, which also appear in Vieta's formulas. Weierstrass's theorem uses these to achieve a uniform approximation, and Cardano's theorem is used to solve a specific type of them. There are no general solutions to these expressions with degree (*) five or higher, and they can be simplified using synthetic division. Functions of this type are all continuous and differentiable, and they have at least one complex root according to the fundamental theorem of algebra. For ten points, identify these algebraic expressions that contain variables raised to a power, such as 2y and 3x plus 1.
Output (English): Science
