    Work: Find the solution of equation -300+649/(1+x)+488/(1+x)/(1+x)+1591/(1+x)/(1+x)/(1+x)+1719/(1+x)/(1+x)/(1+x)/(1+x)+1539/(1+x)/(1+x)/(1+x)/(1+x)/(1+x) = 0 .
    Question type: Equation
    Solution:Original question:
      - 300 + 649 ÷ (1 + x ) + 488 ÷ (1 + x ) ÷ (1 + x ) + 1591 ÷ (1 + x ) ÷ (1 + x ) ÷ (1 + x ) + 1719 ÷ (1 + x ) = 0
     Multiply both sides of the equation by:(1 + x )
      - 300(1 + x ) + 649 + 488 ÷ (1 + x ) + 1591 ÷ (1 + x ) ÷ (1 + x ) + 1719 ÷ (1 + x ) ÷ (1 + x ) ÷ (1 + x ) = 0
    Remove a bracket on the left of the equation::
      - 300 × 1300 x + 649 + 488 ÷ (1 + x ) + 1591 ÷ (1 + x ) ÷ (1 + x ) + 1719 ÷ (1 + x ) = 0
    The equation is reduced to :
      - 300300 x + 649 + 488 ÷ (1 + x ) + 1591 ÷ (1 + x ) ÷ (1 + x ) + 1719 ÷ (1 + x ) ÷ (1 + x ) = 0
    The equation is reduced to :
     349300 x + 488 ÷ (1 + x ) + 1591 ÷ (1 + x ) ÷ (1 + x ) + 1719 ÷ (1 + x ) ÷ (1 + x ) ÷ (1 + x ) = 0
     Multiply both sides of the equation by:(1 + x )
     349(1 + x )300 x (1 + x ) + 488 + 1591 ÷ (1 + x ) + 1719 ÷ (1 + x ) ÷ (1 + x ) + 1539 = 0
    Remove a bracket on the left of the equation:
     349 × 1 + 349 x 300 x (1 + x ) + 488 + 1591 ÷ (1 + x ) + 1719 ÷ (1 + x ) = 0
    The equation is reduced to :
     349 + 349 x 300 x (1 + x ) + 488 + 1591 ÷ (1 + x ) + 1719 ÷ (1 + x ) ÷ (1 + x ) = 0
    The equation is reduced to :
     837 + 349 x 300 x (1 + x ) + 1591 ÷ (1 + x ) + 1719 ÷ (1 + x ) ÷ (1 + x ) + 1539 = 0
     Multiply both sides of the equation by:(1 + x )
     837(1 + x ) + 349 x (1 + x )300 x (1 + x )(1 + x ) + 1591 + 1719 ÷ (1 + x ) = 0
    Remove a bracket on the left of the equation:
     837 × 1 + 837 x + 349 x (1 + x )300 x (1 + x )(1 + x ) + 1591 = 0
    The equation is reduced to :
     837 + 837 x + 349 x (1 + x )300 x (1 + x )(1 + x ) + 1591 + 1719 = 0
    The equation is reduced to :
     2428 + 837 x + 349 x (1 + x )300 x (1 + x )(1 + x ) + 1719 ÷ (1 + x ) = 0
     Multiply both sides of the equation by:(1 + x )
     2428(1 + x ) + 837 x (1 + x ) + 349 x (1 + x )(1 + x )300 x (1 + x ) = 0
    Remove a bracket on the left of the equation:
     2428 × 1 + 2428 x + 837 x (1 + x ) + 349 x (1 + x )(1 + x )300 = 0
    The equation is reduced to :
     2428 + 2428 x + 837 x (1 + x ) + 349 x (1 + x )(1 + x )300 x = 0
    The equation is reduced to :
     4147 + 2428 x + 837 x (1 + x ) + 349 x (1 + x )(1 + x )300 x = 0
     Multiply both sides of the equation by:(1 + x )
     4147(1 + x ) + 2428 x (1 + x ) + 837 x (1 + x )(1 + x ) + 349 x (1 + x ) = 0
    Remove a bracket on the left of the equation:
     4147 × 1 + 4147 x + 2428 x (1 + x ) + 837 x (1 + x )(1 + x ) + 349 = 0
    The equation is reduced to :
     4147 + 4147 x + 2428 x (1 + x ) + 837 x (1 + x )(1 + x ) + 349 x = 0
    The equation is reduced to :
     5686 + 4147 x + 2428 x (1 + x ) + 837 x (1 + x )(1 + x ) + 349 x = 0
