Answer 1

Ответ:

Объяснение:

4a(a-2)-(a-4)²= 4a²-8a-(a²-8a+16)=4a²-8a-a²+8a-16=

=3a²-16

2(m+1)²-4m=2(m²+2m+1)-4m= 2m²+4m+2-4m=2m²+2

Answer 2

To simplify the given expression, let's solve it step by step:

1. Simplify the expression within parentheses: 4a(a - 2) - (a - 4)^2

   Expand the square using the formula (a - b)^2 = a^2 - 2ab + b^2: 4a(a - 2) - (a^2 - 2(a)(-4) + (-4)^2) 4a(a - 2) - (a^2 + 8a - 16) 4a^2 - 8a - a^2 - 8a + 16 (4a^2 - a^2) + (-8a - 8a) + 16 3a^2 - 16a + 16

2. Simplify the second part of the expression: 2(m + 1) - 4m

   Distribute the 2: 2m + 2 - 4m

   Combine like terms: -2m + 2

Now, we have the simplified expression: 3a^2 - 16a + 16 - 2m + 2

The final simplified expression is: 3a^2 - 16a - 2m + 18
