Question 756516

x+8     x^2 + 12x +28

x+8=0 
x=-8

-8             1       12        28
                 0       -8       -32
                 1        +4       -4 ( Remainder) 

Answer is  x+4 

                                     OR 
                                        x+4    
                                       
           x+8                     x^2 + 12x +28
                                      x^2  + 8x
                                      -       -
                                         0   + 4x  + 28
                                              + 4x   +32
                                                 -        - 
                                                  0   +  -4
Quotient is x+ 4
Remainder is -4

 I think 1st method is easy if u still don't understand i will help u online to explain thanks
