[ 1/1 Equation]
    Work: Find the solution of equation (10+x)(500-10x) = 8750 .
    Question type: Equation
    Solution:Original question:
     (10 + x )(50010 x ) = 8750
    Remove the bracket on the left of the equation:
     Left side of the equation = 10(50010 x ) + x (50010 x )
                                             = 10 × 50010 × 10 x + x (50010 x )
                                             = 5000100 x + x (50010 x )
                                             = 5000100 x + x × 500 x × 10 x
                                             = 5000 + 400 x x × 10 x
    The equation is transformed into :
     5000 + 400 x x × 10 x = 8750

    After the equation is converted into a general formula, it is converted into:
    ( x - 15 )( x - 25 )=0
    From
        x - 15 = 0
        x - 25 = 0

    it is concluded that::
        x1=15
        x2=25
    
    There are 2 solution(s).
