[ 1/1 Equation]
    Work: Find the solution of equation 300(1+x)(1+x) = 1092 .
    Question type: Equation
    Solution:Original question:
     300(1 + x )(1 + x ) = 1092
    Remove the bracket on the left of the equation:
     Left side of the equation = 300 × 1(1 + x ) + 300 x (1 + x )
                                             = 300(1 + x ) + 300 x (1 + x )
                                             = 300 × 1 + 300 x + 300 x (1 + x )
                                             = 300 + 300 x + 300 x (1 + x )
                                             = 300 + 300 x + 300 x × 1 + 300 x x
                                             = 300 + 300 x + 300 x + 300 x x
                                             = 300 + 600 x + 300 x x
    The equation is transformed into :
     300 + 600 x + 300 x x = 1092

    The solution of the equation:
        x1≈-2.907878 , keep 6 decimal places
        x2≈0.907878 , keep 6 decimal places
    
    There are 2 solution(s).
