Suku banyak begin mathsize 14px style x to the power of 4 minus a x cubed plus open parentheses a plus 1 close parentheses x squared plus open parentheses a plus 2 close parentheses x plus open parentheses a plus 3 close parentheses space end style jdibagi dengan begin mathsize 14px style x squared minus 2 x minus 3 end style, dengan metode bersusun 

begin mathsize 14px style long division by straight x squared plus straight x plus 1 yields table row cell straight x squared end cell cell plus open parentheses negative straight a minus 1 close parentheses straight x plus 2 straight a plus 1 end cell end table table row blank end table pile table row cell up diagonal strike straight x to the power of 4 end strike minus ax cubed plus open parentheses straight a plus 1 close parentheses straight x squared plus open parentheses straight a plus 2 close parentheses straight x plus open parentheses straight a plus 3 close parentheses end cell blank end table table row cell table row cell up diagonal strike straight x to the power of 4 end strike plus straight x cubed end cell cell plus straight x squared space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space end cell blank blank end table end cell blank end table end pile end long division space space space space space space space space space space space space space space space space space space space space ________________ space minus space space space space space space space space space space space space space space space space space space space space space space up diagonal strike open parentheses negative straight a minus 1 close parentheses straight x cubed end strike plus ax squared plus left parenthesis straight a plus 2 right parenthesis straight x plus left parenthesis straight a plus 3 right parenthesis space space space space space space space space space space space space space space space space space space space space space up diagonal strike left parenthesis negative straight a minus 1 right parenthesis straight x cubed end strike plus open parentheses negative straight a minus 1 close parentheses straight x squared plus open parentheses negative straight a minus 1 close parentheses straight x space space space space space space space space space space space space space space space space space space space _____________________________ space minus space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space up diagonal strike space open parentheses 2 straight a plus 1 close parentheses straight x squared end strike plus open parentheses 2 straight a plus 3 close parentheses straight x plus left parenthesis straight a plus 3 right parenthesis space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space up diagonal strike left parenthesis 2 straight a plus 1 right parenthesis straight x squared end strike plus open parentheses 2 straight a plus 1 close parentheses straight x plus open parentheses 2 straight a plus 1 close parentheses space space space space space space space space space space space space space space space space space space space space _________________________________ space minus space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space 2 straight x minus straight a plus 2 end style   

bersisa begin mathsize 14px style negative 2 a x plus b end style, maka :

begin mathsize 14px style table attributes columnalign right center left columnspacing 2px end attributes row cell negative 2 ax plus straight b end cell equals cell 2 straight x plus open parentheses negative straight a plus 2 close parentheses end cell row blank blank blank row cell rightwards double arrow negative 2 ax end cell equals cell 2 straight x end cell row cell negative 2 straight a end cell equals 2 row straight a equals cell negative 1 end cell row blank blank blank row cell rightwards double arrow straight b end cell equals cell negative straight a plus 2 end cell row straight b equals cell negative open parentheses negative 1 close parentheses plus 2 end cell row straight b equals 3 end table end style  
 

Jadi begin mathsize 14px style straight a over straight b equals negative 1 third end style 

Jadi, tidak ada pilihan jawaban yang tepat
