Perhatikan bahwa Sehingga bisa kita simpulkan bahwa Maka Kemudian, perhatikan bahwa Sehingga bisa kita simpulkan bahwa Maka Sehingga kita peroleh Dari kesamaan matriks di atas, kita peroleh Jadi

Perhatikan bahwa

begin mathsize 14px style straight A squared equals open parentheses table row 1 cell negative 1 end cell row 0 1 end table close parentheses open parentheses table row 1 cell negative 1 end cell row 0 1 end table close parentheses equals open parentheses table row 1 cell negative 2 end cell row 0 1 end table close parentheses straight A cubed equals open parentheses table row 1 cell negative 2 end cell row 0 1 end table close parentheses open parentheses table row 1 cell negative 1 end cell row 0 1 end table close parentheses equals open parentheses table row 1 cell negative 3 end cell row 0 1 end table close parentheses straight A to the power of 4 equals open parentheses table row 1 cell negative 3 end cell row 0 1 end table close parentheses open parentheses table row 1 cell negative 1 end cell row 0 1 end table close parentheses equals open parentheses table row 1 cell negative 4 end cell row 0 1 end table close parentheses  end style  

Sehingga bisa kita simpulkan bahwa

begin mathsize 14px style straight A to the power of straight n equals open parentheses table row 1 cell negative open parentheses straight n minus 1 close parentheses end cell row 0 1 end table close parentheses open parentheses table row 1 cell negative 1 end cell row 0 1 end table close parentheses equals open parentheses table row 1 cell negative straight n end cell row 0 1 end table close parentheses end style 

Maka 

begin mathsize 14px style straight A to the power of 2019 equals open parentheses table row 1 cell negative open parentheses 2019 minus 1 close parentheses end cell row 0 1 end table close parentheses open parentheses table row 1 cell negative 1 end cell row 0 1 end table close parentheses equals open parentheses table row 1 cell negative 2019 end cell row 0 1 end table close parentheses end style 

Kemudian, perhatikan bahwa

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell straight B squared end cell equals cell open parentheses table row 1 0 row cell negative 1 end cell 1 end table close parentheses open parentheses table row 1 0 row cell negative 1 end cell 1 end table close parentheses equals open parentheses table row 1 0 row cell negative 2 end cell 1 end table close parentheses end cell row cell straight B cubed end cell equals cell open parentheses table row 1 0 row cell negative 2 end cell 1 end table close parentheses open parentheses table row 1 0 row cell negative 1 end cell 1 end table close parentheses equals open parentheses table row 1 0 row cell negative 3 end cell 1 end table close parentheses end cell row cell straight B to the power of 4 end cell equals cell open parentheses table row 1 0 row cell negative 3 end cell 1 end table close parentheses open parentheses table row 1 0 row cell negative 1 end cell 1 end table close parentheses equals open parentheses table row 1 0 row cell negative 4 end cell 1 end table close parentheses end cell end table end style 

Sehingga bisa kita simpulkan bahwa

begin mathsize 14px style straight B to the power of straight n equals open parentheses table row 1 0 row cell negative open parentheses straight n minus 1 close parentheses end cell 1 end table close parentheses open parentheses table row 1 0 row cell negative 1 end cell 1 end table close parentheses equals open parentheses table row 1 0 row cell negative straight n end cell 1 end table close parentheses end style 

Maka

begin mathsize 14px style straight B to the power of 2019 equals open parentheses table row 1 0 row cell negative open parentheses 2019 minus 1 close parentheses end cell 1 end table close parentheses open parentheses table row 1 0 row cell negative 1 end cell 1 end table close parentheses equals open parentheses table row 1 0 row cell negative 2019 end cell 1 end table close parentheses end style 

Sehingga kita peroleh

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell straight A to the power of 2019 plus straight B to the power of 2019 end cell equals cell open parentheses table row straight a straight b row straight c straight d end table close parentheses end cell row cell open parentheses table row 1 cell negative 2019 end cell row 0 1 end table close parentheses plus open parentheses table row 1 0 row cell negative 2019 end cell 1 end table close parentheses end cell equals cell open parentheses table row straight a straight b row straight c straight d end table close parentheses end cell row cell open parentheses table row 2 cell negative 2019 end cell row cell negative 2019 end cell 2 end table close parentheses end cell equals cell open parentheses table row straight a straight b row straight c straight d end table close parentheses end cell end table end style  

Dari kesamaan matriks di atas, kita peroleh

begin mathsize 14px style straight a equals 2 straight b equals negative 2019 straight c equals negative 2019 straight d equals 2 end style
