[ 1/1 Equation]
    Work: Find the solution of equation 200+200(1+x)+200(1+x)(1+x) = 0 .
    Question type: Equation
    Solution:Original question:
     200 + 200(1 + x ) + 200(1 + x )(1 + x ) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 200 + 200 × 1 + 200 x + 200(1 + x )(1 + x )
                                             = 200 + 200 + 200 x + 200(1 + x )(1 + x )
                                             = 400 + 200 x + 200(1 + x )(1 + x )
                                             = 400 + 200 x + 200 × 1(1 + x ) + 200 x (1 + x )
                                             = 400 + 200 x + 200(1 + x ) + 200 x (1 + x )
                                             = 400 + 200 x + 200 × 1 + 200 x + 200 x (1 + x )
                                             = 400 + 200 x + 200 + 200 x + 200 x (1 + x )
                                             = 600 + 400 x + 200 x (1 + x )
                                             = 600 + 400 x + 200 x × 1 + 200 x x
                                             = 600 + 400 x + 200 x + 200 x x
                                             = 600 + 600 x + 200 x x
    The equation is transformed into :
     600 + 600 x + 200 x x = 0
    This equation has no real solution!
