解方程(4x^3-6x^2+5)-(8x^2+3x-6)=
解题(4x^3-6x^2+5)-(8x^2+3x-6)= 方程
简化
(4x3 + -6x2 + 5) + -1(8x2 + 3x + -6) = 0
重新排序条件:
(5 + -6x2 + 4x3) + -1(8x2 + 3x + -6) = 0
删除括号包围 (5 + -6x2 + 4x3)
5 + -6x2 + 4x3 + -1(8x2 + 3x + -6) = 0
重新排序条件:
5 + -6x2 + 4x3 + -1(-6 + 3x + 8x2) = 0
5 + -6x2 + 4x3 + (-6 * -1 + 3x * -1 + 8x2 * -1) = 0
5 + -6x2 + 4x3 + (6 + -3x + -8x2) = 0
重新排序条件:
5 + 6 + -3x + -6x2 + -8x2 + 4x3 = 0
结合相似条件: 5 + 6 = 11
11 + -3x + -6x2 + -8x2 + 4x3 = 0
结合相似条件: -6x2 + -8x2 = -14x2
11 + -3x + -14x2 + 4x3 = 0
解:
11 + -3x + -14x2 + 4x3 = 0
