用适当方法解方程(x+6)²-9=0 x²-2x+1=25 4x²+12x+9=81 3x
x²+3x+9/(x²-27)+6x/(9x-x²)-(x-1)/(6+2x)
求代数式的值 6x+2x²-3x+x²+1 其中x=-5 4x+3xy-x²-9 其中x=
9x+6x²-3(x-2/3x²),其中x=-2 1/4(-4x²+2x-8)-(1/2x
先化简,再求值:1/x+1-3-x/x²-6x+9÷x²+x/x-3,其中x=根号2.
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)谁会解这道方程题
分式方程.x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
x/(x-2)+(x+9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)怎样解这道方程
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
