Question

решите срочно !!!!!!!!!!!!!!! 1 и 2

Answer 1

1) а) $= \frac{y+1}{y}$
б) $\frac{a(a-2)}{(a-2)(a+2)} = \frac{a}{a+2}$
2) a) $\frac{3(a+5)-a(a-3)}{a(a+5)} = \frac{15+a^{2} }{a^{2}+5a }$
б) $\frac{2 x^{2} }{(x-2)(x+2)} - \frac{2x}{x+2} = \frac{2 x^{2} -2 x^{2} +4x}{ x^{2}-4} = \frac{4x}{ x^{2}-4 }$
