Answer:
[tex]3x^{11}+9x^7+5x^3-x+4[/tex]
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 [tex]3x^{11}[/tex].
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
