Question

classify by degree and number of terms.
(2 points each)

9x^2yz
18x^2 + 5ab – 6y
8a – 5

1: i got 4th degree and only 1 term so monomial

2: i got 4th degree and 3 terms so trinomial

3: 1st degree and 2 terms so binomial

Answer 1

i just want to clarify that my answers are correct if not please help me correct them thank you

Answer 2

The degree of a polynomial in one variable is the largest exponent in the polynomial. In Polynomials in two variables,the degree of each term in a polynomial in two variables is the sum of the exponents in each term and the degree of the polynomial is the largest such sum.

9x^2yz = 9 x^2 *y^1*z^1--> Degree is (2 + 1+1) = 4; Monomial

18x^2 + 5a^1b^1 – 6y^1 --> Degree is 2; Trinomial

8a^1 – 5 --> Degree is 1; Binomial
