[ 1/1 Equation]
    Work: Find the solution of equation 8x(x+9) = 112 .
    Question type: Equation
    Solution:Original question:
     8 x ( x + 9) = 112
    Remove the bracket on the left of the equation:
     Left side of the equation = 8 x x + 8 x × 9
                                             = 8 x x + 72 x
    The equation is transformed into :
     8 x x + 72 x = 112

    The solution of the equation:
        x1≈-10.352350 , keep 6 decimal places
        x2≈1.352350 , keep 6 decimal places
    
    There are 2 solution(s).
