计算:1(x+1)(x+2)+1(x+2)(x+3)+1(x+3)(x+4)+…+1(x+100)(x+101)
如何计算 (x+1)(x+2)(x+3)(x+4)
计算(X-1)(X-2)(X-3)(X-4)
x+2/x+1-x+3/x+2-x+4/x+3+x+5/x+4
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
计算:(x-1)(x^2-4X+3)-x(x^2-5X+2)有过程
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
1+x+x^2+x^3+.+x^99+x^100
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
计算 x(x+3)-(x-1)(x-2)
计算:(x+1)(x-2)(x-3)(x-6)
计算x/(x^2-1) + (x^-x+1)/(x^3-x^2+x-1)+(x^2+x+1)/(x^3+x^2+x+1)
1x+2x+3x+4x+5x+6x+7x…+99x=100
