Answer:
B: 10n⁵ + 11n³ - 6
Explanation:
(-3 + 3n⁵ + 6n³) + (7n⁵ + 5n³ - 3)
To add the variables, you can only combine the variables with the same degree.
Because you are adding the polynomials, you can remove the parentheses.
-3 + 3n⁵ + 6n³ + 7n⁵ + 5n³ - 3
Now you can combine the variables that are raised to the same degree.
(-3 - 3) + (3n⁵ + 7n⁵) + (6n³ + 5n³)
Now simplify within the parentheses.
(-6) + (10n⁵) + (11n³)
Now reorder the variables from greatest to least degree.
10n⁵ + 11n³ - 6
