Question

представьте в виде дроби
(дробь)y2/y2-25 - (дробь) y/y+5

Answer 1

$\frac{ y^{2} }{ y^{2}-25 }- \frac{y}{y+5} = \frac{ y^{2} }{(y-5)(y+5)} - \frac{y}{y+5}= \frac{ y^{2}- y^{2} +5y }{ y^{2}-25 }= \frac{5y}{ y^{2}-25 }$

Answer 2

y²/y²-25-y/y+5=y²/(y-5)*(y+5)-y/y+5=y²-y*(y-5)/(y-*(y+5)=y²-y²+5y/y²-25=5y/y²-25
