计算3(2x+1)(2x-1)-4(3x-2)(3x+2)+6x(4x+1)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
如何计算 (x+1)(x+2)(x+3)(x+4)
计算(X-1)(X-2)(X-3)(X-4)
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
计算:(x-1)(x^2-4X+3)-x(x^2-5X+2)有过程
计算:(x-1)/(x^2+3x+2)+6/(2+x-x^2)-(10-x)/(4-x^2)
计算:(x+1)(x-2)(x-3)(x-6)
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
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
计算:3/(2x+4)-6/(4-x^2)+1/(x-2);(3x/(x-2)-x/(x+2))*(x^2-4)/x.
计算x^2-5x+6/x^2-1/x^2+x/x-3
