(x+2)(x-13)-16=(x+3)( )
(x+2)(x-13)-16=(x+3)( )

(x+2)(x-13)-16=(x+3)( )
(x+2)(x-13)-16=(x+3)(x-14)

请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360 300字读后感 2篇 俄把格式说一下吧:《xxxx》(写题目)主要内容:x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x(写那篇文章的主要内容)思考分析:x x x (16x^4+4x^2+x)/x=? matlab解数值分析题p=(x-1)*(x-2)*(x-3)*(x-4)*(x-5)*(x-6)*(x-7)*(x-8)*(x-9)*(x-10)*(x-11)*(x-12)*(x-13)*(x-14)*(x-15)*(x-16)*(x-17)*(x-18)*(x-19)*(x-20)解为1,2,3……,20取多个非常小的数用软件工具求解方程p(x)+n*x^19=0,并 (x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)(x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3) (x/x-2)-2=3(x-2)/x x(2x-3)=x² 求x, 解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3) 解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3) (1)X-3/X-1+X²-2/(x-1)(X-7)=1+x-5/x-7 (2)2x-1/x+4-5=96/x²-16-1-3x/4-x 1、1/2x=2/x+32、x/x+1=(2x/3x+3)+13、2/x-1=4/x²-14、5/x²+x-1/x²-x=0 4+6X(3x-2)=16x 怎么解方程?注备:X=乘 x=x (x+x)+(x-x)+(x/x)=11.2 (X-3分之x-1-x分之x-4)除以x的平方+3x分之(x+3)(x-2),其中(x-1)(x-2)=0 解九宫格题目(X为未知数)9 X 2 X 7 X 8 X XX X 4 X X 9 X 6 X1 3 X 5 X X X X 24 X X 8 5 X X 1 XX 8 9 4 X 1 6 7 XX 1 X X 3 6 X X 88 X X X X 2 X 3 6X 5 X 6 X X 9 X XX X 7 X 4 X 2 X 1 解下列方程!就三道!解下列方程.1、x/x-2 - 1-x²/x²-5x = 2x/x-3(x/x-2 - 1-x²不是一起的!)2、5x/x²+x-6 - 5-2x/x²-x-12=7x-10/x²-6x+8(5x/x²+x-6 - 5-2x不是一起的!)3、x-4/x-5 + x-8/x-9=x-7/x- 1.(x+1)(2x-3)-(x-1)(x+2)=x.x+71.(x+1)(2x-3)-(x-1)(x+2)=x.x+72.(2x+1)(4x.x-2x+1)-2x(4x.x+1)=03.(x-3)(x+2)=x.x-16 (1)(2x/x-1)-(x-1/x)=1 (2)(x^2-4x/x^2-1)+1=2x/x+1 (3)(x+4/x^2+2x)-(1/x+2)=(2/x)+1
