计算:(4x^4-6x^2+2)(5x^3-2x^2+x-1),
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
计算:(x-1)(x^2-4X+3)-x(x^2-5X+2)有过程
x/x-3-5x/x^2-x-6计算
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
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
a*b=2×a+b 计算x*2x*3x*4x*5x*6x*7x*8x*9x=3039 x=
计算:(x-1)/(x^2+3x+2)+6/(2+x-x^2)-(10-x)/(4-x^2)
计算[(x²-5x+6)/(x²-4x+3)]+[(x²-4x+3)/(x²-2
计算1/(x^2-3x+2)+1/(x^2-5x+6)+1/(x^2-4x+3)
