Answer:
[tex]{x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10[/tex]
Step-by-step explanation:
To write a polynomial in descending order means writing the polynomial in decreasing powers of x.
The given polynomial expresion is
[tex] - 4 {x}^{5} + 4 {x}^{3} + {x}^{7} - 10 + 2 {x}^{4} [/tex]
We start from the term with the highest degree and end with term with the least degree.
[tex] {x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10[/tex]
Therefore the given polynomial written in descending order is
[tex]{x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10[/tex]
