79642=7x()+9x()+6x()+4x()+2x()求解
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
求解(x²-4/x²-4x+4 +2-x/x+2)除以x/x-2等于多少
(x-4)*2+x=73求解
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
2(x-3)=3x(x-3)求解 x²-4x+2=0
7x-3(2/3x+1/5x)-(x+2/5x)+2x 求解?
1、x*(x+3)*(x+6)*(x+9)=68040 2、x*(x+1)*(x+2)*(x+3)*(x+4)=5544
初一数学x*x+2x+5的值为7,请求3x*x+6x+3的值.因为x*x+2x2x+3=3x(x*x+2x)+2x+2x
求解方程(4X^2)+(400/X^2)
(3X-1)(X+2)=11X-4方程求解
