Помогите пожалуйста,сижу и туплю
p+3\p+4 - p-2\p-4

Answer 1

Объяснение:

$p + \frac{3}{p} + 4 - p - \frac{2}{p} - 4 = \frac{3}{p} - \frac{2}{p} = \frac{1}{p}$

Answer 2

$\frac{p+3}{p+4}-\frac{p-2}{p-4}=\frac{(p+3)*(p-4)-(p-2)*(p+4)}{(p+4)(p-4)}=\frac{p^{2}-4p+3p-12-p^{2}-4p+2p+8}{(p+4)(p-4)} =\frac{-3p-4}{p^{2}-4^{2}}=\\\\=-\frac{3p+4}{p^{2}-16 }$
