=601
360x+(x-360)(180-x)=600*360
360x+180x-180*360-x^2+360x-360*600=0
-x^2+900x-360*780=0
判别式=-313200小于0
原方程 无解
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,

请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,=x^2/x(x-2)+(2x-4)/x(x^2-4)-(x^2+6x)/x(x^2-4)=x^2/x(x-2)-(x+2)/x(x-2)=(x-2)(x+1)/x(x-2)=(x+1)/x
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
填九宫格帮帮忙.x x 6 x x 7 x x 98 x x x 3 x 1 x x 9 x x 6 x 5 x 3 x x x 3 x x x x 1 8x x x 9 x 1 x x x2 1 x x x x 6 x x x 6 x 7 x 3 x x 1 x x 9 x 2 x x x 47 x x 8 x x 5 x x
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
1.用公式计算:COSX=1-X*X/2!X*X*X*X/4!-X*X*X*X*X*X/6!.直到最后一项的绝对
x+(x/360-1)(180-x)=600等于多少?x+(x/360-1)(180-x)=600等于多少,
180=( )x( )x( )x( ) ×( )
X(X-1)=X
x+[x+1/6x]+[x-1/6]=6
5x/x(1+x)=6/1+x
6/(x-1)-(x+2)/x(x-1)=0
[3/x]-[4/x-1]=6/x-x²
[3/x]-[4/x-1]=6/x-x²
