解方程9x^2=(x-2)^2
解方程:(x-2)(x^2-6x-9)=x(x-5)(x-3)
解方程:2x(x-9x)+16=0
9x^2+6x=5x解方程
解方程 5x+6x-9=2x
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-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
解方程 x*x*x + 2*x -19 =0
解方程 (X-3)(X^2+3X+9)-X(X^2+3)-9=9
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
