Question

Choose a term from the Key Vocabulary list above that best describes the given expression.

$x^3+2x^2-3x-1$

Short answer

The given expression can be best described as thestandard form of a polynomial.

Step-by-step solution

Step 1. Define an expression.

A mathematical expression is a combinations of numbers and variables ordered with mathematical operations.

Step 2. Define the meaning of standard form of a polynomial.

The standard form of a polynomial means, writing the polynomial in descending powers of the variable.

Step 3. Write the best description for the expression, x3+2x2−3x−1.

Observe the expression, $x^3+2x^2-3x-1$.

The terms of the polynomial are written in descending powers of $x$.

Therefore the given expression can be best described as the standard form of a polynomial.
