Question

(3m-2²)-2(m-2)(m-3)+(2m-1)(2m+1)​

Answer 1

Ответ:

= 2m^+13-17

Объяснение:

(3m-4)+(-2m+4)×(m-3)+4m^-1

3m-4-2m^-12+4m^-1

13m-17+2m^

Answer 2

Let's simplify the given expression step by step:

(3m - 2²) - 2(m - 2)(m - 3) + (2m - 1)(2m + 1)

First, let's simplify the terms inside the parentheses:

(3m - 4) - 2(m² - 3m - 2m + 6) + (4m² - 1)

Now distribute the constants outside the parentheses:

3m - 4 - 2m² + 6m + 4 + 4m² - 1

Combine the like terms:

(3m - 2m² + 6m + 4m²) + (-4 + 4 - 1)

Now combine the like terms in each grouping:

(9m - 2m²) + (-1)

Combine the last terms:

9m - 2m² - 1

So, the simplified expression is:

9m - 2m² - 1
