Determine the type and degree of each of the following polynomial expressions. 9xy,

x-3y+7x,

19ab+8abc-27a

Monomial of degree 2Binomial of degree 1Trinomial of degree 3

Step-by-step explanation:

9xy

It has one term = monomialIt has a product of two variables of each degree = 1*2 = degree 2

x-3y+7x = 8x - 3y

It has 2 therms = binomialIt has 2 variables of degree one = degree 1

 

19ab+8abc-27a = 8abc + 19ab - 27a

It has 3 terms = trinomialIt has 3 variables, the greatest degree is the product of 3 of them of the first degree = 1 *3 = degree 3
