10x - 2 = 12(x-1)
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
x*x+2x+x*x+10x+x*x+25+2x+x*x+1+1+16+x*x+4x*x+9-12x+16x*x+4-1
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
(2x-2)(x-1)=0 x(x-5)=5x-10
(X-X*20%-18-(X-X*20%-18)*10%=X*1/2-3(过程)
x/2+x/8+x/12+x/20=1
解一元二次方程 3x²=10x+83x²-10x+3=0(x+8)(x+1)=-12(x+1)(2x
x-1=3x+3 x-3=12-4x 6x-14=5x-10 x+1=2-4x
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
