Please simplify this: x/y[2(y^2-4)-5/x(2+y)] It's on a mandatory enrichment program I'm in but we've never covered it...

OpenStudy (anonymous):

x/y[ 2(y-2)(y+2)/x(2+y)] x/y[2(y-2)/x] Can you continue from here?

OpenStudy (anonymous):

Would that turn into (2xy-4x/x^2)/y...?

OpenStudy (anonymous):

Cancel x also from there 2(y -2)/y

OpenStudy (anonymous):

So x = -2?
