X/10-X/16=3
X+(3X-16)÷25%=10(x+1)
X/10-X/16=3
2x平方+3x=3 (用配方) x(2x-5)=4x-10 x平方+5x+7=3x+11 1-8x+16x平方=2-8x
x+3x=-16
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),
解方程:x^2/9+16/x^2=10/3(x/3-4/x)
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
配方法解方程 x²+10x+16=0 x²-x-3/4=0 3x²+6x-5=0 4x
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
解方程(4x^3+10x^2+16x+1)/(2x^2+5x+7)=(6x^3+10x^2+5x-1)/(3x^2+5x
1x()+2x()+3x()+4x()+5x()+6x()+7x()+8x()加9x()+10x()=1980
