Jawaban:

1. Suku banyak $begin mathsize 14px style p open parentheses x close parentheses end style$ dibagi oleh $begin mathsize 14px style open parentheses x squared minus 1 close parentheses end style$ sisanya $begin mathsize 14px style open parentheses negative x plus 4 close parentheses end style$ , artinya :

$begin mathsize 14px style straight p open parentheses straight x close parentheses colon open parentheses straight x squared minus 1 close parentheses space bersisa open parentheses negative straight x plus 4 close parentheses rightwards double arrow open parentheses straight x plus 1 close parentheses open parentheses straight x minus 1 close parentheses rightwards double arrow straight x equals negative 1 space atau space straight x equals 1 maka space semicolon table attributes columnalign right center left columnspacing 2px end attributes row cell straight p open parentheses negative 1 close parentheses end cell equals cell negative straight x plus 4 end cell row blank equals cell negative open parentheses negative 1 close parentheses plus 4 end cell row blank equals 5 row blank blank blank row cell straight p open parentheses 1 close parentheses end cell equals cell negative straight x plus 4 end cell row blank equals cell negative open parentheses 1 close parentheses plus 4 end cell row blank equals 3 end table end style$

2. Suku banyak $begin mathsize 14px style p open parentheses x close parentheses end style$ dibagi oleh $begin mathsize 14px style open parentheses x plus 3 close parentheses end style$ sisanya 11, artinya :

$begin mathsize 14px style table attributes columnalign right center left columnspacing 2px end attributes row cell straight p open parentheses straight x close parentheses space colon space open parentheses straight x plus 3 close parentheses end cell rightwards arrow cell sisa space 11 end cell row blank rightwards double arrow cell straight x equals negative 3 end cell row cell straight p open parentheses negative 3 close parentheses end cell equals 11 end table end style$

3. Jika Suku banyak $begin mathsize 14px style p open parentheses x close parentheses end style$ dibagi oleh $begin mathsize 14px style open parentheses x squared plus 2 x minus 3 close parentheses end style$ anggap sisanya $begin mathsize 14px style ax plus straight b end style$

$begin mathsize 14px style table attributes columnalign right center left columnspacing 2px end attributes row cell straight P open parentheses straight x close parentheses space colon space open parentheses straight x squared plus 2 straight x minus 3 close parentheses end cell rightwards arrow cell sisa space ax plus straight b end cell row cell open parentheses straight x plus 3 close parentheses open parentheses straight x minus 1 close parentheses end cell equals 0 row cell straight x equals negative 3 end cell blank cell atau space straight x equals 1 end cell row artinya colon blank row cell straight p open parentheses negative 3 close parentheses end cell equals cell ax plus straight b rightwards arrow sisa space 11 end cell row 11 equals cell negative 3 straight a plus straight b... open parentheses pers.1 close parentheses end cell row blank blank blank row cell straight p open parentheses 1 close parentheses end cell equals cell ax plus straight b rightwards arrow sisa space 5 end cell row 5 equals cell straight a plus straight b... open parentheses pers. space 2 close parentheses end cell end table end style$

Kemudian pers. 1 dan pers. 2 dieliminasi untuk memperoleh nilai a

$Error converting from MathML to accessible text.$

Selanjutnya nilai b disubstitusikan ker pers. 2

$begin mathsize 14px style table attributes columnalign right center left columnspacing 2px end attributes row cell straight a plus straight b end cell equals 5 row cell negative 3 over 2 plus straight b end cell equals 5 row straight b equals cell 5 times open parentheses negative 2 over 3 close parentheses end cell row straight b equals cell negative 10 over 3 end cell end table end style$

sisa pembagian suku banyak oleh $begin mathsize 14px style open parentheses x squared plus 2 x minus 3 close parentheses end style$ adalah $begin mathsize 14px style equals negative 3 over 2 straight x minus 10 over 3 end style$
