\]
Solution
Solution Steps
To determine the name and degree of the polynomial, we need to count the number of terms and identify the highest power of the variable. A polynomial with one term is a monomial, two terms is a binomial, three terms is a trinomial, and more than three terms is simply called a polynomial. The degree of the polynomial is the highest exponent of the variable.
Step 1: Identify the Type of Polynomial
A polynomial is classified based on the number of terms it contains:
A monomial has one term.
A binomial has two terms.
A trinomial has three terms.
A polynomial with more than three terms is simply called a polynomial.
The given polynomial is:
\[
2x^3 + 3x^2 + 6x
\]
This polynomial has three terms: \(2x^3\), \(3x^2\), and \(6x\). Therefore, it is a trinomial.
Step 2: Determine the Degree of the Polynomial
The degree of a polynomial is the highest power of the variable \(x\) in the polynomial. In the given polynomial:
\[
2x^3 + 3x^2 + 6x
\]
The degrees of the terms are:
\(2x^3\) has a degree of 3.
\(3x^2\) has a degree of 2.
\(6x\) has a degree of 1.
The highest degree among these is 3. Therefore, the degree of the polynomial is 3.
