Question

$\frac{-125}{ X^{2} -5X} + \frac{ X^{2} }{X-5}$

Answer 1

=-125/x(x-5)+x²/(x-5)=
=(-125+x²·x)/x(x-5)=
=(-125+x³)/x(x-5)
=[(x+5)(x-5)(x+5)]/x(x-5)]=simplif cu x-5=
=(x+5)²/x
cond x≠0
(x+5)²=0
x₁=x₂=-5

Answer 2

-125/X(X-5)+X²/X-5=
-125+X²xX/x(x-5)=
-125+X³/X(X-5)=
X³-125/X(X-5)=
X³-5³/X(X-5)
