    解方程,一元一次,二元一次,一元二次,二元二次,一元三次

    解题(x-1)(x^2-4)+2(x-1)(x+2)=(x-1)P 方程

    简化
    (x + -1)(x2 + -4) + 2(x + -1)(x + 2) = (x + -1) * P
    
    重新排序条件:
    (-1 + x)(x2 + -4) + 2(x + -1)(x + 2) = (x + -1) * P
    
    重新排序条件:
    (-1 + x)(-4 + x2) + 2(x + -1)(x + 2) = (x + -1) * P
    
    乘以 (-1 + x) * (-4 + x2)
    (-1(-4 + x2) + x(-4 + x2)) + 2(x + -1)(x + 2) = (x + -1) * P
    ((-4 * -1 + x2 * -1) + x(-4 + x2)) + 2(x + -1)(x + 2) = (x + -1) * P
    ((4 + -1x2) + x(-4 + x2)) + 2(x + -1)(x + 2) = (x + -1) * P
    (4 + -1x2 + (-4 * x + x2 * x)) + 2(x + -1)(x + 2) = (x + -1) * P
    (4 + -1x2 + (-4x + x3)) + 2(x + -1)(x + 2) = (x + -1) * P
    
    重新排序条件:
    (4 + -4x + -1x2 + x3) + 2(x + -1)(x + 2) = (x + -1) * P
    (4 + -4x + -1x2 + x3) + 2(x + -1)(x + 2) = (x + -1) * P
    
    重新排序条件:
    4 + -4x + -1x2 + x3 + 2(-1 + x)(x + 2) = (x + -1) * P
    
    重新排序条件:
    4 + -4x + -1x2 + x3 + 2(-1 + x)(2 + x) = (x + -1) * P
    
    乘以 (-1 + x) * (2 + x)
    4 + -4x + -1x2 + x3 + 2(-1(2 + x) + x(2 + x)) = (x + -1) * P
    4 + -4x + -1x2 + x3 + 2((2 * -1 + x * -1) + x(2 + x)) = (x + -1) * P
    4 + -4x + -1x2 + x3 + 2((-2 + -1x) + x(2 + x)) = (x + -1) * P
    4 + -4x + -1x2 + x3 + 2(-2 + -1x + (2 * x + x * x)) = (x + -1) * P
    4 + -4x + -1x2 + x3 + 2(-2 + -1x + (2x + x2)) = (x + -1) * P
    
    结合相似条件: -1x + 2x = 1x
    4 + -4x + -1x2 + x3 + 2(-2 + 1x + x2) = (x + -1) * P
    4 + -4x + -1x2 + x3 + (-2 * 2 + 1x * 2 + x2 * 2) = (x + -1) * P
    4 + -4x + -1x2 + x3 + (-4 + 2x + 2x2) = (x + -1) * P
    
    重新排序条件:
    4 + -4 + -4x + 2x + -1x2 + 2x2 + x3 = (x + -1) * P
    
    结合相似条件: 4 + -4 = 0
    0 + -4x + 2x + -1x2 + 2x2 + x3 = (x + -1) * P
    -4x + 2x + -1x2 + 2x2 + x3 = (x + -1) * P
    
    结合相似条件: -4x + 2x = -2x
    -2x + -1x2 + 2x2 + x3 = (x + -1) * P
    
    结合相似条件: -1x2 + 2x2 = 1x2
    -2x + 1x2 + x3 = (x + -1) * P
    
    重新排序条件:
    -2x + 1x2 + x3 = (-1 + x) * P
    
    重新排列条件以便更容易乘法解决:
    -2x + 1x2 + x3 = P(-1 + x)
    -2x + 1x2 + x3 = (-1 * P + x * P)
    -2x + 1x2 + x3 = (-1P + xP)
    
    解:
    -2x + 1x2 + x3 = -1P + xP
    
    求解变量 'x'.
    
    重新排序条件:
    P + -2x + -1xP + 1x2 + x3 = -1P + xP + P + -1xP
    
    重新排序条件:
    P + -2x + -1xP + 1x2 + x3 = -1P + P + xP + -1xP
    
    结合相似条件: -1P + P = 0
    P + -2x + -1xP + 1x2 + x3 = 0 + xP + -1xP
    P + -2x + -1xP + 1x2 + x3 = xP + -1xP
    
    结合相似条件: xP + -1xP = 0
    P + -2x + -1xP + 1x2 + x3 = 0
    
    无法确定此方程的解.
