10*50% +X*5%=(10+X)*25%,
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
用C语言编写程序,用牛顿迭代法求高次方程f(x)=5*x*x*x*x*x-8*x*x*x+10*x*x-7x+25=0的
(x+5)²-(x-2)(x-3) =x²+10x+25-(x²-5x+6) *5x怎么来
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
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
(x+7/x+6)+ (x+9/+x+8)=(x+10/x+9)+(x+6/x+5)
1.x+9/x+8- x+10/x+9=x+6/x+5- x+7/x+6;
⒈ 解方程 (X+7)/(X+6)+(X+9)/(X+8)=(X+10)/(X+9)+(X+6)/(X+5)
x-4/x-6+x-8/x-10=x-5/x-7+x-7/x-9
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
1x()+2x()+3x()+4x()+5x()+6x()+7x()+8x()加9x()+10x()=1980
