Answer:
4x² + 3x² - 7x² + 3x + 2
Explanation:
o arrange the polynomials in descending order of their degrees, you need to group them by their degree and then order those groups from highest degree to lowest degree. In this case, you have:
4x² (degree 2)
3x² (degree 2)
-7x² (degree 2)
3x (degree 1)
2 (degree 0)
Now, arrange them in descending order of their degrees:
4x²
3x²
-7x²
3x
2
So, the polynomials in descending order of their degrees are:
4x² + 3x² - 7x² + 3x + 2
