8y-3(3y+2)=68y-3(3y+2)=68y-3(3y+2)=6
8y-3(3y+2)=6
8y-3(3y+2)=6
8y-3(3y+2)=6
y (3y^2+8y-3)-6y(3y+2y-1)+9y
(y^2)^4y-(-2y)^3y^6=
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
解方程:(y-3y+2)(y+3y-2)=y(y+3)(y-3)
求方程 8y-3(3y-2)68y-3(3y-2)=6
8y-3(3y+2)=6
4y(3y-2)-2y(6y+5)>8解不等式
(y+1)分之(2y+3)=(3y+4)分之(6y+7)
解方程:(y+4)/5+y+6=(y+8)/2-(y+4)/3要过程
1.5y+8y-6y=2y-3咋做?
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
[T,Y]=ode45(@rigid,[0 1],[rand(15,1)]);plot(T,Y(:,1),'-',T,Y(:,2),'-.',T,Y(:,3),'.',T,Y(:,4),'-',T,Y(:,5),'-.',T,Y(:,6),'.',T,Y(:,7),'-',T,Y(:,8),'-.',T,Y(:,9),'.',T,Y(:,10),'-',T,Y(:,11),'-.',T,Y(:,12),'-.',T,Y(:,13),'.',T,Y(:,14),'-',T,Y(:,15),'.')
1.((y+2x)(-2x+y)+4(x+2y)^2)/3y 2.(2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2)/2(x-y)^2
2y方+3y+7=8,则4y方+6y-9的值(详细过程)
6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算
2y+5/3y-6-y/2=5y-4/2y-4
-2y(y-3)=-3(6-2)y
-2y(y-3)=-3(6-2)y
