(x+2)(x-1)+(x+3)(x+1)=x·x-1 求x (5x-4)(2x+5)(3x-6)(2x-4)=(2x-4)(2x+5)·0.5 求x
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
2x+3x+4x+5x+x+6x+7x=100
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
X(x平方-6x-9)-x(x平方-8x-15)+2x(3-x)其中x=-六分之一
3.268=3X()+2X()+6X()+8X()
(x+2)(x-3)(x-6)(x-1)=0
3X*X-2X+6=8,X=?3X*X-2X+6=8,X=?则代数式1.5X*X-X+1=?
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8 好多年没有用过过数学公式了 想不起来怎么算了 想知道 X值是多少
已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^+x^6+x^7+x^8的值
如果1+x+x^2+x^3=0,求x+x^2+X^3+x^4+x^5+x^6+x^7+x^8的值,
已知x=2π+1求 |x-1|+|x-2|+|x-3|+|x-4|+|x-5|+|x-6|+|x-7|+|x-8|+|x-9|+|x-10|
已知x=2π+1.求(X-1)+(X-2)+(X-3)+(X-4)+(X-5)+(X-6)+(X-7)+(X-8)+(X-9)+(X-10)
1/(x*x-2x-3)+2/(x*-x-6)+3/(x*x+3x+2)=0
