Pembahasan

Jawaban yang benar untuk pertanyaan tersebut adalah table attributes columnalign right center left columnspacing 0px end attributes row cell p with rightwards arrow on top minus q with rightwards arrow on top end cell equals cell open parentheses table row cell negative 12 end cell row 15 end table close parentheses end cell end table.

Misalkan diketahui vektor a with rightwards arrow on top equals open parentheses table row cell x subscript a end cell row cell y subscript a end cell end table close parentheses dan vektor b with rightwards arrow on top equals open parentheses table row cell x subscript b end cell row cell y subscript b end cell end table close parentheses. Pengurangan dua vektor tersebut dapat dirumuskan sebagai berikut.

a with rightwards arrow on top minus b with rightwards arrow on top equals open parentheses table row cell x subscript a end cell row cell y subscript a end cell end table close parentheses minus open parentheses table row cell x subscript b end cell row cell y subscript b end cell end table close parentheses equals open parentheses table row cell x subscript a minus x subscript b end cell row cell y subscript a minus y subscript b end cell end table close parentheses

Diketahui vektor p with rightwards arrow on top equals open parentheses table row cell negative 5 end cell row 6 end table close parentheses dan q with rightwards arrow on top equals open parentheses table row 7 row cell negative 9 end cell end table close parentheses.

table attributes columnalign right center left columnspacing 0px end attributes row cell p with rightwards arrow on top minus q with rightwards arrow on top end cell equals cell open parentheses table row cell negative 5 end cell row 6 end table close parentheses minus open parentheses table row 7 row cell negative 9 end cell end table close parentheses end cell row blank equals cell open parentheses table row cell negative 12 end cell row 15 end table close parentheses end cell end table

Dengan demikian, diperoleh table attributes columnalign right center left columnspacing 0px end attributes row cell p with rightwards arrow on top minus q with rightwards arrow on top end cell equals cell open parentheses table row cell negative 12 end cell row 15 end table close parentheses end cell end table.
