Question

Split the middle term for the expression x2+23+104

Answer 1

x² + 23x + 104
multiply last and first term ,

=104.
split 104 such that the numbers if added gives 23 and when multiplied gives 104.

    -104   +   -1   =   -105    
   -52   +   -2   =   -54  
    -26   +   -4   =   -30    
   -13   +   -8   =   -21  
     -8   +   -13   =   -21
    -4   +   -26   =   -30
    -2   +   -52   =   -54  
    -1   +   -104   =  -105  
    1   +   104   =   105    
   2   +   52   =   54    
   4   +   26   =   30    
   8   +   13   =   21    
  13   +   8   =   21    
  26   +   4   =   30    
   52   +   2   =   54    
  104   +   1   =   105

there is no 2 numbers that adds up to 23
so this equation will not have the right combination.so it has no zeroes.


hope it helps!!!!
