[ 1/1 Equation]
    Work: Find the solution of equation t^2*(t^2+1)*(0.25^2*t^2+1) = 25 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, it is converted into:
    ( t + 2 )( t - 2 )=0
    From
        t + 2 = 0
        t - 2 = 0
    it is concluded that:：
        t₁=-2
        t₂=2    
    There are 2 solution(s).
