Question

(2-c)²-c(c+4) при c -1/8

Answer 1

(2-c)²-c(c+4)   при c=·1/8
4-4c+c²-c²-4c=4-8c
если c=-1/8. то 4-8(-1/8)=4+1=5

Answer 2

I can help you with your math problem. Here is the detailed solution:

$$ \begin{aligned} (2-c)^2-c(c+4) &= (4-4c+c^2)-(c^2+4c) \\ &= 4-8c+4c \\ &= 4-4c \end{aligned} $$

When $c=-\frac{1}{8}$, we have:

$$ \begin{aligned} 4-4c &= 4-4\left(-\frac{1}{8}\right) \\ &= 4+\frac{1}{2} \\ &= \frac{9}{2} \end{aligned} $$

Therefore, the final answer is $\frac{9}{2}$. I hope this helps.Ответь+подробно.+(2-c)²-c(c+4)+при+c+-1/8
