[ 1/1 Equation]
    Work: Find the solution of equation 2(1-x)(1-x)(1-x) = x(2-x)(3x-1-x×x) .
    Question type: Equation
    Solution:Original question:
     2(1 − x )(1 − x )(1 − x ) = x (2 − x )(3 x − 1 − x x )
    Remove the bracket on the left of the equation:
     Left side of the equation = 2 × 1(1 − x )(1 − x ) − 2 x (1 − x )(1 − x )
                                             = 2(1 − x )(1 − x ) − 2 x (1 − x )(1 − x )
                                             = 2 × 1(1 − x ) − 2 x (1 − x ) − 2 x (1 − x )(1 − x )
                                             = 2(1 − x ) − 2 x (1 − x ) − 2 x (1 − x )(1 − x )
                                             = 2 × 1 − 2 x − 2 x (1 − x ) − 2 x (1 − x )(1 − x )
                                             = 2 − 2 x − 2 x (1 − x ) − 2 x (1 − x )(1 − x )
                                             = 2 − 2 x − 2 x × 1 + 2 x x − 2 x (1 − x )
                                             = 2 − 2 x − 2 x + 2 x x − 2 x (1 − x )(1 − x )
                                             = 2 − 4 x + 2 x x − 2 x (1 − x )(1 − x )
                                             = 2 − 4 x + 2 x x − 2 x × 1(1 − x ) + 2 x
                                             = 2 − 4 x + 2 x x − 2 x (1 − x ) + 2 x x
                                             = 2 − 4 x + 2 x x − 2 x × 1 + 2 x x
                                             = 2 − 4 x + 2 x x − 2 x + 2 x x + 2
                                             = 2 − 6 x + 2 x x + 2 x x + 2 x x
                                             = 2 − 6 x + 2 x x + 2 x x + 2 x x
                                             = 2 − 6 x + 2 x x + 2 x x + 2 x x
    The equation is transformed into :
     2 − 6 x + 2 x x + 2 x x + 2 x x = x (2 − x )(3 x − 1 − x x )
    Remove the bracket on the right of the equation:
     Right side of the equation = x × 2(3 x − 1 − x x ) − x x (3 x − 1 − x x )
                                               = x × 2 × 3 x − x × 2 × 1 − x × 2 x x − x
                                               = x × 6 x − x × 2 − x × 2 x x − x x (3 x − 1 − x x )
                                               = x × 6 x − 2 x − x × 2 x x − x x × 3
    The equation is transformed into :
     2 − 6 x + 2 x x + 2 x x + 2 x x = x × 6 x − 2 x − x × 2 x x − x x × 3

    The solution of the equation:
        x1≈-1.081019 , keep 6 decimal places
        x2≈0.519466 , keep 6 decimal places
    
    There are 2 solution(s).
