Ingat:

Jika begin mathsize 14px style straight a with rightwards arrow on top end style tegak lurus begin mathsize 14px style straight b with rightwards arrow on top end style maka begin mathsize 14px style straight a with rightwards arrow on top space. space straight b with rightwards arrow on top equals 0 end style

Karena begin mathsize 14px style straight p with rightwards arrow on top end style dan begin mathsize 14px style straight q with rightwards arrow on top end style saling tegak lurus, artinya begin mathsize 14px style straight p with rightwards arrow on top space. space straight q with rightwards arrow on top equals 0 end style

begin mathsize 14px style straight p with rightwards arrow on top space. space straight q with rightwards arrow on top equals 0 open parentheses 2 straight i with rightwards arrow on top minus straight m straight j with rightwards arrow on top plus 3 straight k with rightwards arrow on top close parentheses space. space open parentheses 2 straight i with rightwards arrow on top minus straight j with rightwards arrow on top plus straight m straight k with rightwards arrow on top close parentheses equals 0 4 plus straight m plus 3 straight m equals 0 space space 4 plus 4 straight m equals 0 space space 4 straight m equals negative 4 space space straight m equals negative 1 end style
