通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
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
y''-5y'+6y=3x+1通解
(3y-1)/4-1=(5y-7)/6 9y-3-3=10y-14 9y-10y=-14+3+3 -y=-8 y=8
计算:[(y+1)/(y^2-4y+3)减去(y-2)/(y^2-6y+9)]除以(y-5)/(y-1)
(5y+1)÷6=(9y+1)÷8-(1-y)÷3
5y+1/6=9y+1/8-1-y/3
(5Y+1)/6=(9Y+1)/8-(1-Y)/3
解一元一次方程5y+1/6 = 9y+1/8 - 1-y/3
(y-2)(y^2-6y-9)-y(y^2-2y-15),其中y=1/2.先化简再求值.
常微分方程的通解dy/dx=(x-y+1)/(x+y-3)y^4=2y^n+y=0y''+6y'+9y=e^(-3x)y''+y'-2y=4e^(2x)
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
