Question

(-2mn²+3mn²)-(m²n-3m²+mn²)​

Answer 1

Ответ:m²(3-n)

Объяснение:

-2mn²+3mn²-m²n+3m²-mn²= - m²(n-3)=m²(3-n)

Answer 2

(-2mn²+3mn²)-(m²n-3m²+mn²)=m³n²-2m²n⁴

Answer 3

To simplify the expression (-2mn² + 3mn²) - (m²n - 3m² + mn²), you can start by combining like terms.

Step 1: Distribute the negative sign through the second expression: -2mn² + 3mn² - m²n + 3m² - mn²

Step 2: Combine like terms: (-2mn² + 3mn² - mn²) + (-m²n + 3m²)

Step 3: Perform the addition and subtraction of like terms separately: (3mn² - mn²) + (-m²n + 3m²)

Step 4: Continue simplifying: 2mn² + (-m²n + 3m²)

Now, the expression is simplified as much as possible.
