[ 1/1 Equation]
    Work: Find the solution of equation 350×(1+x)×(1十X) = 504 .
    Question type: Equation
    Solution:Original question:
     350(1 + x )(1 + x ) = 504
    Remove the bracket on the left of the equation:
     Left side of the equation = 350 × 1(1 + x ) + 350 x (1 + x )
                                             = 350(1 + x ) + 350 x (1 + x )
                                             = 350 × 1 + 350 x + 350 x (1 + x )
                                             = 350 + 350 x + 350 x (1 + x )
                                             = 350 + 350 x + 350 x × 1 + 350 x x
                                             = 350 + 350 x + 350 x + 350 x x
                                             = 350 + 700 x + 350 x x
    The equation is transformed into :
     350 + 700 x + 350 x x = 504

    After the equation is converted into a general formula, it is converted into:
    ( 5x + 11 )( 5x - 1 )=0
    From
        5x + 11 = 0
        5x - 1 = 0

    it is concluded that::
        x1=-
11

        x2=

    There are 2 solution(s).
