解方程:x^3-9=9x-x^2
解方程:(x-2)(x^2-6x-9)=x(x-5)(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-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程 (X-3)(X^2+3X+9)-X(X^2+3)-9=9
解方程:2x+9/x+3 - 1/x-3 = 5 - 3x-2/x
解方程 :(2x-3)(-2x-3)+9x=x(3-4x)
解方程4x^2+2x√(3x^+x)+x-9=0
解方程:x-1/x+2 +9/(x+2)(x-1)=3/x-1
解方程4x方+x+2x根号下(3x方+x) =9
解方程 (3x+1)(3x-1)=(x+2)(9x-4) 2(x-3)(x-2)-(x+3)²=(x-1)(x
