Question

2(m+1)²-4mСрочно!!!

Answer 1

$2(m+1)^2-4m=2(m^2+2m+1)-4m=2m^2+4m+2-4m=2m^2+2$

Answer 2

Sure, I can help you with that expression. It seems you want to simplify the given expression. Let's do the math step by step:

1. First, let's expand the squared term (m+1)²: (m+1)² = (m+1)(m+1) = mm + m1 + 1m + 11 = m² + 2m + 1

2. Now, let's substitute the expansion back into the expression: 2(m+1)² - 4m = 2(m² + 2m + 1) - 4m

3. Next, distribute the 2 through the parentheses: 2(m² + 2m + 1) - 4m = 2m² + 4m + 2 - 4m

4. Simplify the terms: 2m² + 4m + 2 - 4m = 2m² + 2

So, the simplified expression is: 2m² + 2.
