Question

N=6,2. −17n(17n+17)+(17n−17)(17+17n).

Answer 1

Ответ:

(17+17n)(-17n+17n-17)=-17²n-17²=2080.8

Answer 2

It looks like you are presenting a mathematical expression: $N = 6.2 - 17n(17n+17) + (17n-17)(17+17n)$. To simplify this expression, let's break it down step by step:

1. Distribute the $-17n$ through $(17n+17)$: $-17n(17n+17) = -289n^2 - 289n$

2. Distribute $(17n-17)$ through $(17+17n)$: $(17n-17)(17+17n) = 289n^2 - 289$

3. Now, substitute these results back into the original expression: $N = 6.2 - (289n^2 + 289n) + (289n^2 - 289)$

4. Simplify further: $N = 6.2 - 289n^2 - 289n + 289n^2 - 289$

5. Combine like terms: $N = 6.2 - 289$

6. Finally, perform the subtraction: $N = -282.8$

So, the simplified form of the given expression is $N = -282.8$.
