[ 1/1 Equation]
    Work: Find the solution of equation 80^2 = 7.68^2+x^2 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, it is converted into:
    ( 25x +√3963136 )( 25x - √3963136 )=0
    From
        25x +√3963136 = 0
        25x - √3963136 = 0

    it is concluded that::
        x1=-
√3963136
25
        x2=
√3963136
25
    
    There are 2 solution(s).
