[ 1/1 Equation]
    Work: Find the solution of equation (200+10x)(64-x) = 14400 .
    Question type: Equation
    Solution:Original question:
     (200 + 10 x )(64 x ) = 14400
    Remove the bracket on the left of the equation:
     Left side of the equation = 200(64 x ) + 10 x (64 x )
                                             = 200 × 64200 x + 10 x (64 x )
                                             = 12800200 x + 10 x (64 x )
                                             = 12800200 x + 10 x × 6410 x x
                                             = 12800200 x + 640 x 10 x x
                                             = 12800 + 440 x 10 x x
    The equation is transformed into :
     12800 + 440 x 10 x x = 14400

    After the equation is converted into a general formula, it is converted into:
    ( x - 4 )( x - 40 )=0
    From
        x - 4 = 0
        x - 40 = 0

    it is concluded that::
        x1=4
        x2=40
    
    There are 2 solution(s).
