EQ . How are polynomials like whole#'s ?

= 2000 t 600+70+5

2×3 t6×2+7×+5

XZ t3×+2

+ 4×2+5X H-

5×2+8×+3

They are the same because they are addinglike terms . They are different

because

polynomials can have coefficients greaterthan9

therefore there is no needfor regrouping .

Also, polynomials can have negaNYt⑧⑧⑧g%qfµ

• All the terms in the second polynomialtreed to be subtracted (Everthingterm opposite)

• Only subtractlike Terms !

• Subtraction can bewritten as addition
