Answer 1

Сначала раскрывай скобки, а потом решай)
2a-2a-2a-2a=-4a

Answer 2

To solve this expression, we can simplify it using the distributive property of multiplication and then combine like terms:

(2a - a^2) - (a^2 + 2a) = 2a - a^2 - a^2 - 2a (distributive property) = -2a^2 (combining like terms)

Therefore, the solution is -2a^2.
