(3 akar 2 - 4 akar 6)*(2 akar 2 + 3 akar 6)
= ((3 akar 2)*(2 akar 2)) + ((3 akar 2)*(3 akar 6)) + ((-4 akar 6)*(2 akar 2)) + ((-4 akar 6)*(3 akar 6))
= (6 akar 4) + (9 akar 12) + (-8 akar 12) + (-12 akar 36)
= 6*2 + (9 akar 4* akar 3) + (-8 akar 4*akar 3) + (-12*6)
= 12 + (9*2*akar 3) + (-8*2*akar 3) +(-72)
= 12 + (18 akar 3) + (-16 akar 3) - 72
= 12 - 72 + 18 akar 3 - 16 akar 3
= -60 + 2 akar 3
