Write 2x3 − 3x2 + x5 in standard form. What is the classification of this polynomial by its degree? by its number of terms?
andrew-mc [135]

Answer:

  x⁵ +2x³ -3x², degree 5, 3 terms

Step-by-step explanation:

We assume you intend your expression to be ...

  2x³ -3x² +x⁵

The superscript numbers are exponents. Each indicates the degree of the term. In standard form, terms are listed in decreasing order by degree:

  x⁵ +2x³ -3x² . . . . standard form

The degree of the polynomial is the degree of the highest-degree term: 5.

The number of terms is the number of products in the sum: 3.
