Polynomial

An algebraic formula consisting of several single-item additions is called a polynomial.
Form: F (x) =∑ni=0aixi f (x) =∑i = 0 N a i x i f (x) =\sum_{i=0}^{n}a_ix^i,
deg f (x) deg F (x) \deg~f (x) is called the degree of F F F, which is the number of times F (x) f (x) f (x) is the highest. Generating Functions

Shaped like ∑∞i=0aixi∑i = 0∞a i x i \sum_{i=0}^\infty a_ix^i
The generating function, also called the female function, is often associated with the polynomial algorithm to optimize the transfer of the function polynomial algorithm plus subtraction

Polynomial addition and subtraction is relatively simple
If f (x) =∑ni=0aixi f (x) =∑i = 0 N a i x i f (x) =\sum_{i=0}^na_ix^i, g (x) =∑ni=0bixi g (x) =∑i = 0 N b i x i g (x) =\sum _{i=0}^nb_ix^i

(f±g) (x) =∑ni=0 (AI
