To write polynomials in descending order..

2. To write a polynomial in descending order:
The term with the greatest exponent is written first.
The term with the next greatest exponent is written next, and so on.
If there is a constant, it is written last.
8x4 + 3x2 –2x +5

3. Example 1: Arrange in descending order for the variable “x”
3x x7 – 4x6
4x7 – 4x6 + 3x + 3

4. Example 2: Arrange in descending order for the variable “x”
7xy5 + 5x3y3 – 3x2y
5x3y3 – 3x2y+ 7xy5

5. Example 3: Arrange in descending order for x
-5x5 + 16x3 + 5x2 - 7x -19

6. Example 4: Arrange in descending order for x
-x5y2 – 9x4 + x3 – x2y3 + 7xy + 10

7. Example 5: Arrange in descending order for x
x4y – 6x3y5 – x2y +x -17

8. Example 6: Collect Like Terms and Then Arrange in Descending Order
4x³ + 3x ²+ 5x³ -2x²
4x³ + 3x ²+ 5x³+ -2x²
9x³ + x²
