2//5(y-3)=1/3y-3/5(y-7)
2//5(y-3)=1/3y-3/5(y-7)
2//5(y-3)=1/3y-3/5(y-7)
8.1
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
解方程:3y²-(2y+1)(y-2)=(y-5)(y+1)
方程5y(2y-3)=(y+2)(y-2)-1
y-(y-1)/2=1-(2y-3)/5
y-y-1/2=3-y+2/5
微分方程y''-3y'+2y=5,y(0)=1,y'(0)=2求解过程
(96/y²16)+(3y-1/4-y)=(2y-1/y+4)-5
y-1/y-2 - y-3/y-4=y-2/y-3 - y-4/y-5一共有四个分数哦~希望可以快一点~谢谢!
(2y+5/3y)²-5y×(5/3y+y)=4 求y的值.(2y+5/3y)的平方-5y×(5/3y+y)=4
5y∧2-(y-2)(3y+1)-2(y+1)(y-5)
2y+5/3y-6-y/2=5y-4/2y-4
解3y+5/3y-6=1/2+5y-4/2y-4
3(Y+1)^2-5(Y+1)(Y-1)+2(Y-1)^2,化简
