Hi Zander

Baie dankie vir jou vraag en bewerking!

Jou eerste probeerslag, wat jy doodgetrek het, was actually reg gewees! Jy moes nog net die finale antwoord geskryf het. (",)
Jou tweede probeerslag was ook reggewees, jy het net 'n skryffout gemaak - die 2a in die tweede wortel moes net 'n 8a gewees het: 2 square root of 2 a cross times 8 a end root minus 6 square root of 2 a cross times 18 a end root rightwards double arrow 2 square root of 2 a cross times 8 a end root minus 6 square root of 8 a cross times 18 a end root. Behalwe daarvoor is jou bewerkings perfek!
