Answer 1

Y-y²(y-x)^-1/1+x²(y²-x²)^-1
= y-y²(y²-x²)^1/1+x²(y-x)^1
y²-x²= (y+x)(y-x)
jadi
y-y²(y-x)(y+x) /1+x²(y-x)^1
=y-y²(y+x)/1+x²
2.(x^-2 - y^-2)^-1/( (x^-1-y^-1)²)^-1
= ((x^-1- y^-1)(x^-1+y^-1)) ^-1/( (x^-1-y^-1)²)^-1
= (x^-1+y^-1)^-1/ (x^-1- y^-1)^-1

= (x^-1-y^-1)/ (x^-1+ y^-1)

maaf kalo ada yg salah
