Write this polynomial in standard form: -2x^-1+5x-x^3 square

## Step 1: Identify the terms of the polynomial.### The given polynomial is . The terms are , , and .## Step 2: Arrange the terms in descending order of exponents.### A polynomial in standard form has its terms arranged from the highest degree to the lowest degree. The term with the highest degree is (degree 3), followed by (degree 1). The term is not considered in standard form because it has a negative exponent.## Step 3: Write the polynomial in standard form.### Arranging the terms in descending order of exponents, we get .
