Lavoisier organized a list of the known
elements of his day as four categories.
Newlands was the first to organize the
elements and show that properties repeated in a periodic way. Mendeleev and Meyer proposed periodic tables showing a relationship between atomic mass and elemental properties. Moseley organized the elements by atomic number instead of atomic mass.

17.1 understanding polynomial expressions answer key

KiRa [710]

The identification of the polynomial expression is as follows:

Binomial, degree 2
Trinomial degree 6
Monomial, degree 4

<h3>What is a polynomial?</h3>

A polynomial shows the relation of more than two algebraic terms and the sum of powers of a polynomial in more than one variable. Polynomials are represented in terms of $\mathbf{kx^n}$ ;

where;

k = any number
n = positive integer.

The degree of a polynomial expressions can be:

Monomial
Binomial
Trinomial

Let's assume we have the following equation;

6b² - 7
x²y - 9x⁴y²+ 3xy
35r³s

Their degree of polynomial expression is:

Binomial, degree 2
Trinomial degree 6
Monomial, degree 4
