(4.5+X)X3.6/2=18 5X-5=3X+11
(4.5+X)X3.6/2=18 5X-5=3X+11
(4.5+X)X3.6/2=18
4.5+x=18x2/3.6
4.5+x=10
x=10-4.5
x=5.5
5X-5=3X+11
5x-3x=5+11
2x=16
x=8
(4.5+X)X3.6/2=18 5X-5=3X+11
6x+5x2-3x3+2x-7x3,其中x=-5
X3 +5X -6
x3+5x-6
x3+5x+18=0 ,x3指X的三次方,求X
x3+x+2 x3-4x2-4x-5 因式分解
X3+X=2 X3为X的立方
x3+5x+6因式分解
设x=(1-√5)÷2则√(x3-1÷x3)x3就是x³
X3+3X+5=7则3X3+9X-2等于多少
2x3-6x2+6x=1,x是多少
方程(5x-2)x3=5x怎么写?
25+(x-25)x3/8=x/2-5
5x+(9-x)x3=35
(1/5x+x)x3=8
1.x^2-x-202.(x-4)(x+5)=4-x3.x^2+6x-5=04.2x^2-4x-1=0
1.证明(8-7x-6x2+x3)+(x3+5x2+4x-1)-(-x2-3x+2x3-3)的值与x无关.快,
求证:无论X取何值下列(8-7X-6X2+X3)+(X3+5X2+4X-1)-(-X2-3X+2X3-3)结果不变
