2x=(x-9)+22的解,
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程:x(x的平方-2)+2x的平方(x+3)-3x(5x-7)=x(3x的平方-9x+17)+2
2x=(x-9)+22的解,
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
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
解方程:(x-2)(x^2-6x-9)=x(x-5)(x-3)
