: Hi i'm trying to work out on the practice Test on my txtbook & i'm not sure with my answer can you please help me...
48)Denominators are additive inverses.Add pr subtract as indicated.Simplify the result if possible.
(y-7)/(y^2-16) + (7-y)/(16-y^2)
I did the cross multiplication
(16y-y^3-112+7y^2) / (7y^2-y3-112+16y)
(-y^3 +7y^2 +16y-112)/(-y^3 +7y^2 +16y-112)
what will be the answer is it 1 or 0?
Did I do the right thing? or there is another solution?
Looking forward for your reply.
Thanks
