解方程X%+(1+X%)X%=44%
解方程 8.4x+x=1.2(3+x)
1.5x+1.2x(210-x)=300
一元二次方程解答!x(5x+4)=5x+44x^2-45=31x-3x^2+22x-24=0(x+8)(x+1)= -12(3x+2)(x+3)=x+14
1.8/1.2=(x+3)/x
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
2*【x+(x+40)】=400
(X+X)+(X-X)+(X*X)+(X/X)=100
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
400=x^2+(x+x)^2
x/(120-x)=x/60
已知x除以(x*x-x+1)=7,求x*x除以(x*x*x*x+x*x+1)的值
