整函数P(x)=x^4-3x^3+4x-12
解题P(x)=x^4-3x^3+4x-12
简化
P(x) = x4 + -3x3 + 4x + -12
乘以 P * x
xP = x4 + -3x3 + 4x + -12
重新排序条件:
xP = -12 + 4x + -3x3 + x4
解:
xP = -12 + 4x + -3x3 + x4
求解变量 'x'.
重新排序条件:
12 + -4x + xP + 3x3 + -1x4 = -12 + 4x + -3x3 + x4 + 12 + -4x + 3x3 + -1x4
重新排序条件:
12 + -4x + xP + 3x3 + -1x4 = -12 + 12 + 4x + -4x + -3x3 + 3x3 + x4 + -1x4
结合相似条件: -12 + 12 = 0
12 + -4x + xP + 3x3 + -1x4 = 0 + 4x + -4x + -3x3 + 3x3 + x4 + -1x4
12 + -4x + xP + 3x3 + -1x4 = 4x + -4x + -3x3 + 3x3 + x4 + -1x4
结合相似条件: 4x + -4x = 0
12 + -4x + xP + 3x3 + -1x4 = 0 + -3x3 + 3x3 + x4 + -1x4
12 + -4x + xP + 3x3 + -1x4 = -3x3 + 3x3 + x4 + -1x4
结合相似条件: -3x3 + 3x3 = 0
12 + -4x + xP + 3x3 + -1x4 = 0 + x4 + -1x4
12 + -4x + xP + 3x3 + -1x4 = x4 + -1x4
结合相似条件: x4 + -1x4 = 0
12 + -4x + xP + 3x3 + -1x4 = 0
无法确定此方程的解.
