计算3(2X+1)-2[4X-(3X-1)]算得好,我就,就.

计算(x+1)(x+2)(x+3)(x+4) 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)-24计算 计算:[(x^2 - 4)/(x^2 - x - 6) + (x+2)/(x-3)] / (x+1)/(x-3) 计算：(2x+3)(3x-4)>(x+1)(x-1)+5x(x+3)+7 计算：(x-1)(x^2-4X+3)-x(x^2-5X+2)有过程 计算:[(x+2)/(x+3) - (x+1)/(x+2) + (x+4)/(x+5) - (x+3)/(x+4) / (x^2 + 7x + 13)/(x^2 + 8x + 15) 计算(x+2)/(x+1) - (x+3)/(x+2) + (x+4)/(x+3) - (x+5)/(x+4) 如何计算（x-1)(x-2)(x-3)(x-4)-(x^2-5x)^2-10(x^2-5x) 计算（x*x+4x+5）/（x+2）-（x*x+6x+10）/（x+3）+1 计算：（x+1)(x-2)(x-3)(x-6) 计算 x(x+3)-(x-1)(x-2） 计算：x/(x-1)-(x+3)/(x^-1)*(x^2+2x+1)/(x+3) 计算：1-2x+x^2/x-x^3*xy+x^2y/x-x^2 计算-4x(3x²-2x-1) 计算-4x(3x²-2x-1) *-----------------------------------------------*| 6 4 X | 8 X X | X X 5 || X X X | X X X | X 7 8 || X X X | X X X | X X X ||---------------+---------------+--------------- || X X X | X X X | 5 1 X || X X X | X 6 X | X X X || 8 X X | 3 5 X | 2 X X ||
