[ 1/1 Equation]
    Work: Find the solution of equation 120(1+x)(1+x) = 570 .
    Question type: Equation
    Solution:Original question:
     120(1 + x )(1 + x ) = 570
    Remove the bracket on the left of the equation:
     Left side of the equation = 120 × 1(1 + x ) + 120 x (1 + x )
                                             = 120(1 + x ) + 120 x (1 + x )
                                             = 120 × 1 + 120 x + 120 x (1 + x )
                                             = 120 + 120 x + 120 x (1 + x )
                                             = 120 + 120 x + 120 x × 1 + 120 x x
                                             = 120 + 120 x + 120 x + 120 x x
                                             = 120 + 240 x + 120 x x
    The equation is transformed into :
     120 + 240 x + 120 x x = 570

    The solution of the equation:
        x1≈-3.179449 , keep 6 decimal places
        x2≈1.179449 , keep 6 decimal places
    
    There are 2 solution(s).
