Answer 2

Ответ:

(7а-13ав+10b^2) +(-3a^2 +10ab-7b^2) =

7a-13ab+10b^2 - 3a^2 +10ab-7b^2 =

7a-3ab+3b^2 - 3a^2

Answer 3

To simplify the expression $(7a - 13ab + 10b²) + (-3a² + 10ab - 7b²)$, you need to combine like terms. Like terms have the same variables raised to the same powers. In this case, the terms with variables $a$ and $b$ are like terms.

Let's simplify the expression step by step:

Starting expression: $7a - 13ab + 10b² + (-3a² + 10ab - 7b²)$

Step 1: Combine the $a$ terms: $7a - 3a² = 4a - 3a²$

Step 2: Combine the $ab$ terms: $-13ab + 10ab = -3ab$

Step 3: Combine the $b²$ terms: $10b² - 7b² = 3b²$

Now, put the simplified terms back together:

$4a - 3a² - 3ab + 3b²$

So, the simplified expression is $4a - 3a² - 3ab + 3b²$.
