▼优质解答
答案和解析
6y+12/y^2+4y+4-y^2-4/y^-4y+4+y^2/y^2-4=0
6(y+2)/(y+2)^2-(y+2)(y-2)/(y-2)^2+y^2/(y+2)(y-2)=0
6/(y+2)-(y+2)/(y-2)+y^2/(y+2)(y-2)=0
6(y-2)-(y+2)^2+y^2=0
6y-12-y^-4y-4+y^2=0
2y-16=0
y=8
6(y+2)/(y+2)^2-(y+2)(y-2)/(y-2)^2+y^2/(y+2)(y-2)=0
6/(y+2)-(y+2)/(y-2)+y^2/(y+2)(y-2)=0
6(y-2)-(y+2)^2+y^2=0
6y-12-y^-4y-4+y^2=0
2y-16=0
y=8
