解方程3x^3-9x^2-10x=x^3-2x^2-2x-28

解题3x^3-9x^2-10x=x^3-2x^2-2x-28 方程

简化
3x3 + -9x2 + -10x = x3 + -2x2 + -2x + -28

重新排序条件:
-10x + -9x2 + 3x3 = x3 + -2x2 + -2x + -28

重新排序条件:
-10x + -9x2 + 3x3 = -28 + -2x + -2x2 + x3

解：
-10x + -9x2 + 3x3 = -28 + -2x + -2x2 + x3

求解变量 'x'.

重新排序条件:
28 + -10x + 2x + -9x2 + 2x2 + 3x3 + -1x3 = -28 + -2x + -2x2 + x3 + 28 + 2x + 2x2 + -1x3

结合相似条件: -10x + 2x = -8x
28 + -8x + -9x2 + 2x2 + 3x3 + -1x3 = -28 + -2x + -2x2 + x3 + 28 + 2x + 2x2 + -1x3

结合相似条件: -9x2 + 2x2 = -7x2
28 + -8x + -7x2 + 3x3 + -1x3 = -28 + -2x + -2x2 + x3 + 28 + 2x + 2x2 + -1x3

结合相似条件: 3x3 + -1x3 = 2x3
28 + -8x + -7x2 + 2x3 = -28 + -2x + -2x2 + x3 + 28 + 2x + 2x2 + -1x3

重新排序条件:
28 + -8x + -7x2 + 2x3 = -28 + 28 + -2x + 2x + -2x2 + 2x2 + x3 + -1x3

结合相似条件: -28 + 28 = 0
28 + -8x + -7x2 + 2x3 = 0 + -2x + 2x + -2x2 + 2x2 + x3 + -1x3
28 + -8x + -7x2 + 2x3 = -2x + 2x + -2x2 + 2x2 + x3 + -1x3

结合相似条件: -2x + 2x = 0
28 + -8x + -7x2 + 2x3 = 0 + -2x2 + 2x2 + x3 + -1x3
28 + -8x + -7x2 + 2x3 = -2x2 + 2x2 + x3 + -1x3

结合相似条件: -2x2 + 2x2 = 0
28 + -8x + -7x2 + 2x3 = 0 + x3 + -1x3
28 + -8x + -7x2 + 2x3 = x3 + -1x3

结合相似条件: x3 + -1x3 = 0
28 + -8x + -7x2 + 2x3 = 0
