subtract
(13a^2-6a^5-2a)-(-10a^2-11a^5+9a)
To subtract these two algebraic expressions, we need to combine like terms.
(13a^2 - 6a^5 - 2a) - (-10a^2 - 11a^5 + 9a)
First, distribute the negative sign to the terms within the parentheses:
13a^2 - 6a^5 - 2a + 10a^2 + 11a^5 - 9a
Next, we can combine like terms:
(13a^2 + 10a^2) + (-6a^5 + 11a^5) + (-2a - 9a)
This simplifies to:
23a^2 + 5a^5 - 11a
Therefore, the result of the subtraction is 23a^2 + 5a^5 - 11a.
