则么算(x-3)*(x-2)*(x-1)*x=360
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
[x(x+1)+x平方(x-1)]+(-3x)
(x-1)^3(x+1)(x-2)/(x+4)
(x+1)(x+2)(x+3)(x+4)+1
f(x)=x²+3x|x-2|
计算 x(x+3)-(x-1)(x-2)
解方程1/x(x+1)+1/(x+1)(x+2)+...+1/(x+8)(x+9)=2x+3/x(x+9)
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
6/(x+1)=(x+5)/[x(x+1)] (3-x)/(x-4)+1/(4-x)=1 2/(1+x)-3/(1-x)
x(x^2-1)+2x^2 *(x+1)-3x*(2x-5)=x(3x^2-4x)-28
