(3y-1)^2=(y-3)^2
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
1.5y+8y-6y=2y-3
(y^2-3y+2)(y^2+3y-2)=y^2(y+3)(y-3)
(3x-y)^2+(3x+y)(3x-y),x=1,y=-2
解方程(1-3y)^2+(2y-1)^2=13(y-1)(y+1)
解3y+5/3y-6=1/2+5y-4/2y-4
微分方程y''=3√y,x=0,y=1,y'=2
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
y+y^-1=3 求y+y^-2等于几
解方程,3y^3+(y+3)(6-2y)+3y(y+2)(2-y)-2(y^2+1)=0
[(2x+y)^2+(y+2x)(y-2x)-2y(4x-y)]/4y,其中x=1/2,y=1/3
