[ 1/1 Equation]
    Work: Find the solution of equation (5+x)*(5+x)+24*24 = (27-x)*(27-x) .
    Question type: Equation
    Solution:Original question:
     (5 + x )(5 + x ) + 24 × 24 = (27 x )(27 x )
     Left side of the equation = (5 + x )(5 + x ) + 576
    The equation is transformed into :
     (5 + x )(5 + x ) + 576 = (27 x )(27 x )
    Remove the bracket on the left of the equation:
     Left side of the equation = 5(5 + x ) + x (5 + x ) + 576
                                             = 5 × 5 + 5 x + x (5 + x ) + 576
                                             = 25 + 5 x + x (5 + x ) + 576
                                             = 601 + 5 x + x (5 + x )
                                             = 601 + 5 x + x × 5 + x x
                                             = 601 + 10 x + x x
    The equation is transformed into :
     601 + 10 x + x x = (27 x )(27 x )
    Remove the bracket on the right of the equation:
     Right side of the equation = 27(27 x ) x (27 x )
                                               = 27 × 2727 x x (27 x )
                                               = 72927 x x (27 x )
                                               = 72927 x x × 27 + x x
                                               = 72954 x + x x
    The equation is transformed into :
     601 + 10 x + x x = 72954 x + x x

    
        x=2
