Question

x/x+1 + x/x^2+x va rogggg rapiddddddddddd

Answer 1

Explicație pas cu pas:

$\frac{x}{x + 1} + \frac{x}{ {x}^{2} } + x = \frac{^{x)} x}{x + 1} + \frac{^{x + 1)}1}{x} + ^{x(x + 1))}x = \frac{ {x}^{2} + x + 1 + {x}^{3} + {x}^{2} }{x(x + 1)} = \frac{ {x}^{3} + 2{x}^{2} + x + 1}{x(x + 1)}$

Answer 2

$\it x\in\mathbb{R}\setminus\{-1,\ 0\}\\ \\ \\ \dfrac{x}{x+1}+\dfrac{x}{x^2+x}=\dfrac{x}{x+1}+\dfrac{x}{x(x+1)}=\dfrac{x}{x+1}+\dfrac{1}{x+1}=\dfrac{x+1}{x+1}=1$
