[ 1/1 Equation]
    Work: Find the solution of equation 3000+200x+5%x*(3000+200x) = 4700 .
    Question type: Equation
    Solution:Original question:
     3000 + 200 x +
5
100
 x (3000 + 200 x ) = 4700
    Remove the bracket on the left of the equation:
     Left side of the equation = 3000 + 200 x +
5
100
 x × 3000 +
5
100
 x × 200 x
                                             = 3000 + 200 x + 150 x + 10 x x
                                             = 3000 + 350 x + 10 x x
    The equation is transformed into :
     3000 + 350 x + 10 x x = 4700

    The solution of the equation:
        x1≈-39.323153 , keep 6 decimal places
        x2≈4.323153 , keep 6 decimal places
