y-3/4y-8÷(5/y-2-y-2) 计算`
y-3/4y-8÷(5/y-2-y-2) 计算`
y-3/4y-8÷(5/y-2-y-2) 计算`
原式 = y/4 - 8y/(1-y)(5+y) = (y^2-4y+27)y/4(y-1)(y+5)
6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算
计算y-3/4y-8÷(y+2-5/y-2)
y-3/4y-8÷(5/y-2-y-2) 计算`
(y-3)/(4y-8)÷(y+2-5/(y-2))
y-3/4y-8÷(5/y-2 -y-2) 一道数学题,
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
y (3y^2+8y-3)-6y(3y+2y-1)+9y
4y²-4y/y²-2y+1÷(y+1/y-1-y-1/y+1)÷(3y+3)
2y+5/3y-6-y/2=5y-4/2y-4
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y= -2分之5先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y= -2分之5
4x-3y/x-2y÷6y-8x/y-2x
y-3/4y-8/(y+2-5/y-2)这如何化简
4y(3y-2)-2y(6y+5)>8解不等式
解方程:(y+4)/5+y+6=(y+8)/2-(y+4)/3要过程
3y-2(10-y)=4y-5(8-y)
(3y+2)(y-4)-3(y-2)(y-3)
(y^2)^4y-(-2y)^3y^6=
