Question

Which of the following shows the polynomial below written in descending order 3x^3+9x^7-x+4x^12

Answer 1

`4x^(12)+9x^7+3x^3-x`

To write it in descending order, order the terms by their degree from least to greatest.

Answer 2

The answer is
`4x^1^2+9x^7+3x^3-x`

Explanation:

In order to determine the correct expression, we have to know about the order of a polynomial.

In a polynomial, every term has a order which is represented by its power. A term is the variable and its power.

In this case, the variable is "x" with different powers. To order the polynomial in descending form, we have to express every term from the highest power to the lowest power.

Finally the descending polynomial is:

`4x^1^2+9x^7+3x^3-x`
