[ 1/1 Equation]
    Work: Find the solution of equation 500*(1+X%)x1000*(1+0.5X%) = 660000 .
    Question type: Equation
    Solution:Original question:
     500(1 + X ) X × 1000(1 +
1
2
X ) = 660000
     Left side of the equation = 500000(1 + X ) X (1 +
1
2
X )
    The equation is transformed into :
     500000(1 + X ) X (1 +
1
2
X ) = 660000
    Remove the bracket on the left of the equation:
     Left side of the equation = 500000 × 1 X (1 +

X )
                                             = 500000 X + 250000 X X + 500000 X X × 1 + 500000 X X
                                             = 500000 X + 250000 X X + 500000 X X + 250000 X X X
    The equation is transformed into :
     500000 X + 250000 X X + 500000 X X + 250000 X X X = 660000

    The solution of the equation:
        X1≈-198.652902 , keep 6 decimal places
        X2≈-102.641844 , keep 6 decimal places
        X3≈1.294746 , keep 6 decimal places
    
    There are 3 solution(s).
