[ 1/1 Equation]
    Work: Find the solution of equation 500(1+x)(1.08+x) = 112 .
    Question type: Equation
    Solution:Original question:
     500(1 + x )(
27
25
+ x ) = 112
    Remove the bracket on the left of the equation:
     Left side of the equation = 500 × 1(
27
25
+ x ) + 500 x (
27
25
+ x )
                                             = 500(
27
25
+ x ) + 500 x (
27
25
+ x )
                                             = 500 ×
27
25
+ 500 x + 500 x (
27
25
+ x )
                                             = 540 + 500 x + 500 x (
27
25
+ x )
                                             = 540 + 500 x + 500 x ×
27
25
+ 500 x x
                                             = 540 + 500 x + 540 x + 500 x x
                                             = 540 + 1040 x + 500 x x
    The equation is transformed into :
     540 + 1040 x + 500 x x = 112

    The solution of the equation:
        x1≈-1.514974 , keep 6 decimal places
        x2≈-0.565026 , keep 6 decimal places
    
    There are 2 solution(s).
