(96/y²16)+(3y-1/4-y)=(2y-1/y+4)-5

(96/y²16)+(3y-1/4-y)=(2y-1/y+4)-5
(96/y²16)+(3y-1/4-y)=(2y-1/y+4)-5

(96/y²16)+(3y-1/4-y)=(2y-1/y+4)-5
你的题目应该是:(96/y²16)+(3y-1)/(4-y)=(2y-1)/(y+4)-5 对吗?
(96/y²16)+(3y-1)/(4-y)=(2y-1)/(y+4)-5
方程式左右都乘以y²16*(4-y)*(y+4),得到
96(4-y)(y+4)+16y²(3y-1)(y+4)=16y²(2y-1)(4-y)-5*16y²(4-y)(y+4)
化简后
-96y²+96*16+48y^4+176y^3-64y²=-32y^4+144y^3-64y^2+80y^4-1280y^2
32y^3+1184y^2+1536=0
y^3+37y^2+48=0
