Question

Which of the following shows the polynomial below written in descending order? 5x3 – x + 9x7 + 4 + 3x11

Answer 1

`3x^(11)+9x^7+5x^3-x+4`

Explanation:

To write a polynomial in descending order, we arrange the terms by their exponents.

The largest exponent we have is 11; this makes the first term in the order
`3x^(11)`.

The next largest exponent we have is 7; this makes the second term in the order 9x⁷.

The next largest exponent we have is 3; this makes the third term in the order 5x³.

The next largest exponent we have is 1; this makes the fourth term in the order -x¹, which is the same as -x.

The last term will be 4.

This makes the order 3x¹¹ + 9x⁷ + 5x³ - x + 4

Answer 2

There are no options to choose from above. Assuming the last numbers in the terms are exponents, this is what it should look like in descending exponent order.

3x^11 + 9x^7 + 5x^3 - x + 4
