[ 1/1 Equation]
    Work: Find the solution of equation (5x-2)*(8x-2) = 10 .
    Question type: Equation
    Solution:Original question:
     (5 x 2)(8 x 2) = 10
    Remove the bracket on the left of the equation:
     Left side of the equation = 5 x (8 x 2)2(8 x 2)
                                             = 5 x × 8 x 5 x × 22(8 x 2)
                                             = 40 x x 10 x 2(8 x 2)
                                             = 40 x x 10 x 2 × 8 x + 2 × 2
                                             = 40 x x 10 x 16 x + 4
                                             = 40 x x 26 x + 4
    The equation is transformed into :
     40 x x 26 x + 4 = 10

    The solution of the equation:
        x1≈-0.180594 , keep 6 decimal places
        x2≈0.830594 , keep 6 decimal places
    
    There are 2 solution(s).
