Question

(a^3+27)-(3a-a^2)= ,(a^3+27)-(3a-a^2)=

Answer 1

Сначала то что в скобках, а потом остальное решаем

Answer 2

To simplify the expression, let's combine like terms:

(a^3 + 27) - (3a - a^2)

Now, distribute the negative sign across the second parenthesis:

= a^3 + 27 - 3a + a^2

Next, rearrange the terms so that they are in descending order of powers of 'a':

= a^3 + a^2 - 3a + 27

So, the simplified expression is: a^3 + a^2 - 3a + 27.
