polynomial

x+3y-5 <<<<應該 4個都唔係.......(如果 y 唔係常數)

binomial 姐係二項式 佢個名講左 佢有2個項
e.g. (x+2)^5 le 個就係一條2項式.....
trinormial (x^2 + 3x +10) ^5 le d 係三項式

polynormial 佢既意思只要大過一就夠
y+1 y^2 + y +1 y^3 + y^2 + y + 1
都係.........

Polynomial: An equation more than one term (2,3,4,5,6,7,8,9,10..........)
Monomial: An equation in one term
Binomial: An equation in two terms
Trinomail: An equation in three terms

(x+3y-5) is a polynomail and trinomial as well because it has three terms.


*Extra information:*
Poly--: More than one. E.g. Polygon, Polytechnic
Bi--: Two. E.g. Bicycle,
Tri --: Three. E.g. Triangle, Tricycle

polynomial=多項式
monomial=單項式
binomial=兩項式
trinomial=三項式
monomial=x[只是有一件物件(x)]
binomial=z+x[有兩件物件(z),(x)]
trinomial=z+x+c[有三件物件(z),(x),(c)]
yes
