y (3y^2+8y-3)-6y(3y+2y-1)+9y

y (3y^2+8y-3)-6y(3y+2y-1)+9y (y^2)^4y-(-2y)^3y^6= 6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算 通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9 y=(y')^3+y' [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 【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2= (3y+2)(y-4)-3(y-2)(y-3) 2y+5/3y-6-y/2=5y-4/2y-4 y(y+4)-y(y-3)-9y详细解答 [(-3-y)-y]^2怎麼算, 求方程 8y-3(3y-2)68y-3(3y-2)=6 数学题=y(y+3)-4(y+3)2=(y+3)(y-4y-12) 4x-3y/x-2y÷6y-8x/y-2x 3(x-y)^2-7(x-y)+8(y-x)^2+6(y-x)合并同类项. 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 81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2
