Pembahasan

Perhatikan bahwa, Sehingga, Jadi, jawaban yang tepat adalah E.

Perhatikan bahwa,

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell PQ with rightwards arrow on top end cell equals cell OQ with rightwards arrow on top minus OP with rightwards arrow on top end cell row blank equals cell straight q with rightwards arrow on top minus straight p with rightwards arrow on top end cell row cell QR with rightwards arrow on top end cell equals cell OR with rightwards arrow on top minus OQ with rightwards arrow on top end cell row blank equals cell straight r with rightwards arrow on top minus straight q with rightwards arrow on top end cell row cell RS with rightwards arrow on top end cell equals cell OS with rightwards arrow on top minus OR with rightwards arrow on top end cell row blank equals cell straight s with rightwards arrow on top minus straight r with rightwards arrow on top end cell end table end style 

Sehingga,

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell PQ with rightwards arrow on top minus QR with rightwards arrow on top plus RS with rightwards arrow on top end cell equals cell straight q with rightwards arrow on top minus straight p with rightwards arrow on top minus open parentheses straight r with rightwards arrow on top minus straight q with rightwards arrow on top close parentheses plus straight s with rightwards arrow on top minus straight r with rightwards arrow on top end cell row blank equals cell straight q with rightwards arrow on top minus straight p with rightwards arrow on top minus straight r with rightwards arrow on top plus straight q with rightwards arrow on top plus straight s with rightwards arrow on top minus straight r with rightwards arrow on top end cell row blank equals cell negative straight p with rightwards arrow on top plus 2 straight q with rightwards arrow on top minus 2 straight r with rightwards arrow on top plus straight s with rightwards arrow on top end cell end table end style 

Jadi, jawaban yang tepat adalah E.space space
