5x(x-3)=6-2x 解方程.
5x(x-3)=6-2x 解方程.
5x(x-3)=6-2x 解方程.
5x(x-3)=6-2x
5x²-15x+2x-6=0
5x²-13x-6=0
﹙5x+2﹚﹙x-3﹚=0
x=-0.4,x=3
5x*x-15x=6-2x
5x*x-15x+2x=6
5x*x-13x-6=0
不知道你第一x是乘还是X
如果是乘就好做了
5x-3=6-2x
5x+2x=6+3
7x=9
x=7/9
是5乘以x-3还是5*X*(x-3)啊
5x(x-3)=6-2x
5x(x-3)=2(3-x)
5x(x-3)=(-2)(x-3)
(x-3)(5x+2)=0
所以
x=3或x=-2/5
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x/(x-2)-(1-x ² )/(x ² -5x+6)=(2-x)/(x-3) 解方程,急
解方程:(x-2)(x^2-6x-9)=x(x-5)(x-3)
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
解方程(x+1/x+2)-(x+2/x+3)=(x+5/x+6)-(x+6/x+7)
解方程:x+2/x+1-x+3/x+2=x+6/x+5-x+7/x+6
解分式方程:(x+1)/(x+2)+(x+6)/(x+7)=(x+2)/(x+3)+(x+5)/(x+6)
解分式方程: (x-1)/(x-2)+(x-6)/(x-7)=(x-2)/(x-3)+(x-5)/(x-6)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
解方程 (x+2)/(x+1) - (x+4)/(x+3)=(x+6)/(x+5)-(x+8)/(x+7)
解方程:6x(7-x)=36-2x(3x-5)x是字母x
解方程:(6x+5x)-(2x-3x)=336
解分式方程x/X-2-1-X^2/X^2-5X+6=2X/X-3
解方程5x+2x+3x+8x+6x=140-x-3x
解分式方程:x-3/x-1-x-4/x-2=x-5/x-3-x-6
解方程x(2x-5)-x(x+2)=x²-6,
