Question

3) (a^2+3ab-b^2)*ab ​

Answer 1

Ответ:

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

Объяснение:

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

Answer 2

To simplify the expression $(a^2 + 3ab - b^2) \cdot ab$, you can distribute the terms:

$(a^2 + 3ab - b^2) \cdot ab = a^2 \cdot ab + 3ab \cdot ab - b^2 \cdot ab$

Now, multiply each term:

$a^2 \cdot ab = a^3b$ $3ab \cdot ab = 3a^2b^2$ $-b^2 \cdot ab = -ab^3$

Combine the terms:

$(a^2 + 3ab - b^2) \cdot ab = a^3b + 3a^2b^2 - ab^3$

So, $(a^2 + 3ab - b^2) \cdot ab$ simplifies to $a^3b + 3a^2b^2 - ab^3$.
