simplify: (y+1)(y/1-y^2)
which answer:
A. Y/y-1
B. y/1-y
C. y+1/y-1
D. -1
this is what i got y+1/1* Y/1-y^2=-1
Derek , how are you
just answer my question
please

thats my name
since you got -1 for your final answer, did you try it to see whether it works? How about y=0?
(0+1)(0/(1-0)) = 0, not -1
assuming you meant
(y+1)(y/(1-y^2))
(y+1)(y) / (1+y)(1-y)
y/(1-y)
(y+1)(y/1-y^2)
(y+1)[y/(1+y)(1-y)]
y/1-y
correct ans is b
