Question

2а²+3в-5в+7ав-2а-а+4в-5ав-а²ав​

Answer 1

2а²+3в-5в+7ав-2а-а+4в-5ав-а²ав = 2а²+2в+7ав-3а-а³в =

а³в + 2а² + 7ав - 3а + 2в

Answer 2

To simplify the expression 2a² + 3b - 5b + 7ab - 2a - a + 4b - 5ab - a²ab, we can combine like terms:

Grouping terms with 'a': 2a² - 2a - a - a²ab = (2a² - a²ab) + (-2a - a) = a²(2 - ab) + (-3a)

Grouping terms with 'b': 3b - 5b + 4b = (3 - 5 + 4)b = 2b

Now, let's put it all together: a²(2 - ab) + (-3a) + 2b

This is the simplified form of the expression.
