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

Step-by-step 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 .

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

45
