5а^2 + 3а - 7 - 5а^3 - 3а^2 + 7а - 11 = -5a^3 +  2а^2 + 10a - 18

Answer 3

To simplify the expression 5а^2 + 3а - 7 - 5а^3 - 3а^2 + 7а - 11, we can combine like terms:

Grouping the terms with the same powers of "а":

(-5а^3) + (5а^2 - 3а^2) + (3а + 7а) + (-7 - 11)

Simplifying the terms within each grouping:

-5а^3 + 2а^2 + 10а - 18

Thus, the simplified form of the expression is -5а^3 + 2а^2 + 10а - 18.
