[ 1/1 Equation]
    Work: Find the solution of equation (X×5)(X×7) = 89999 .
    Question type: Equation
    Solution:Original question:
     ( X × 5)( X × 7) = 89999
    Remove the bracket on the left of the equation:
     Left side of the equation = X × 5( X × 7)
                                             = X × 5 X × 7
                                             = X × 35 X
    The equation is transformed into :
      X × 35 X = 89999

    After the equation is converted into a general formula, it is converted into:
    ( X + 50.708974 )( X - 50.708974 )=0
    From
        X + 50.708974 = 0
        X - 50.708974 = 0

    it is concluded that::
        X1≈-50.708974 , keep 6 decimal places
        X1≈50.708974 , keep 6 decimal places
    Solutions that cannot be obtained by factorization:
        X2=
    
    There are 2 solution(s).
