10(X+2)+X-[10X+(X+2)]=18
(X-X*20%-18-(X-X*20%-18)*10%=X*1/2-3(过程)
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
x+2x×10=10x+2x+36
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
方程:10(x+2)+x-18=10x+x+2 x是未知数
(2x-2)(x-1)=0 x(x-5)=5x-10
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
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),
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
