计算(-3x^3+6x^4-x^5)/(-2x)^2计算(-3x^3+6x^4-x^5)/(-2x)^2计算(-3x^3+6x^4-x^5)/(-2x)^2(-3x^3+6x^4-x^5)/(-2x)

计算(-3x^3+6x^4-x^5)/(-2x)^2
计算(-3x^3+6x^4-x^5)/(-2x)^2

计算(-3x^3+6x^4-x^5)/(-2x)^2
(-3x^3+6x^4-x^5)/(-2x)^2
=(-3x^3)/4x^2+6x^4/4x^2-x^5/4x^2
=-3x/4+3x^2/2-x^3/4

(-3x^3+6x^4-x^5)/(-2x)^2
=-3x/4+3x^2/2-x^3/4

求什么？x的值，还是化简式子？

x/x-3-5x/x^2-x-6计算计算:x/x-2 - 5x/x²-x-6计算:x/x-3 - 5x/x²-x-6 计算（x*x+4x+5）/（x+2）-（x*x+6x+10）/（x+3）+1 计算(x+6)(x+7)-(x-4)(x+3) 计算:[(x^2 - 4)/(x^2 - x - 6) + (x+2)/(x-3)] / (x+1)/(x-3) 计算(6x^4-5x^3-3x^2-x+4)/(2x+4) 计算:(4x^4-6x^2+2)(5x^3-2x^2+x-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 || 计算5(x^2+x-3)-4x(6+x)+x(4-x)=02x(x-1)-x(2x-5) 计算：(x^2+6x+10)/(x^2+6x+9)+(x^2-11)/(x^2-9)+(2x^2+8x+5)/(x^2+4x+3) 计算：5x-(x-3)(x+5) 计算:|3-x|+|x-1|(x>5) 2x*4x-3x计算计算：(2x+3)(3x-4)>(x+1)(x-1)+5x(x+3)+7 计算(x-2)(x-3)+2(x+6)(x-5)-3(x平方-7x+13) 计算:1/(x+3)(x+4)+1/(x+4)(x+5).1/(x+99)(x+100) 计算x^2-5x+6/x^2-1/x^2+x/x-3 x^2+x-6分之x^2+3x-x^2-4分之x+2计算
