3a+2ab-b^2-3a+ab-2b^2=

3ab-3b^2

Answer 2

Ответ:

3ab-3b²

Пошаговое объяснение:

(3a+2ab-b²)-(3a-ab+2b²)=3а-3а+2аb+ab -b²-2b²=3ab-3b²

Answer 3

To simplify the expression (3a + 2ab - b^2) - (3a - ab + 2b^2), you can distribute the negative sign inside the parentheses and then combine like terms:

(3a + 2ab - b^2) - (3a - ab + 2b^2)

= 3a + 2ab - b^2 - 3a + ab - 2b^2

Now, you can group like terms together:

(3a - 3a) + (2ab + ab) + (-b^2 - 2b^2)

Simplify each group of like terms:

0a + 3ab - 3b^2

Since 0a is just 0, you can simplify further:

3ab - 3b^2

So, the simplified expression is:

3ab - 3b^2
