    X^5+4x^4-8x^3-14x^2+7x+10=0

    求解 X^5+4x^4-8x^3-14x^2+7x+10=0 方程:


     

    简化
    X5 + 4x4 + -8x3 + -14x2 + 7x + 10 = 0
    
    重新排序条件:
    10 + X5 + 7x + -14x2 + -8x3 + 4x4 = 0
    
    解:
    10 + X5 + 7x + -14x2 + -8x3 + 4x4 = 0
    
    求解变量 'X'.
    
    移动所有条件 X 到左边,所有其他条件放右边.
    
    添加 '-10' 到等式的每一边.
    10 + X5 + 7x + -14x2 + -8x3 + -10 + 4x4 = 0 + -10
    
    重新排序条件:
    10 + -10 + X5 + 7x + -14x2 + -8x3 + 4x4 = 0 + -10
    
    组合类似条件: 10 + -10 = 0
    0 + X5 + 7x + -14x2 + -8x3 + 4x4 = 0 + -10
    X5 + 7x + -14x2 + -8x3 + 4x4 = 0 + -10
    
    组合类似条件: 0 + -10 = -10
    X5 + 7x + -14x2 + -8x3 + 4x4 = -10
    
    添加 '-7x' 到等式的每一边.
    X5 + 7x + -14x2 + -8x3 + -7x + 4x4 = -10 + -7x
    
    重新排序条件:
    X5 + 7x + -7x + -14x2 + -8x3 + 4x4 = -10 + -7x
    
    组合类似条件: 7x + -7x = 0
    X5 + 0 + -14x2 + -8x3 + 4x4 = -10 + -7x
    X5 + -14x2 + -8x3 + 4x4 = -10 + -7x
    
    添加 '14x2' 到等式的每一边.
    X5 + -14x2 + -8x3 + 14x2 + 4x4 = -10 + -7x + 14x2
    
    重新排序条件:
    X5 + -14x2 + 14x2 + -8x3 + 4x4 = -10 + -7x + 14x2
    
    组合类似条件: -14x2 + 14x2 = 0
    X5 + 0 + -8x3 + 4x4 = -10 + -7x + 14x2
    X5 + -8x3 + 4x4 = -10 + -7x + 14x2
    
    添加 '8x3' 到等式的每一边.
    X5 + -8x3 + 8x3 + 4x4 = -10 + -7x + 14x2 + 8x3
    
    组合类似条件: -8x3 + 8x3 = 0
    X5 + 0 + 4x4 = -10 + -7x + 14x2 + 8x3
    X5 + 4x4 = -10 + -7x + 14x2 + 8x3
    
    添加 '-4x4' 到等式的每一边.
    X5 + 4x4 + -4x4 = -10 + -7x + 14x2 + 8x3 + -4x4
    
    组合类似条件: 4x4 + -4x4 = 0
    X5 + 0 = -10 + -7x + 14x2 + 8x3 + -4x4
