6ab-b^(2)+12ac-2bc

Factorise: 6ab - b ^(2) + 12 ac - 2bc

Factorise : 6ab - b^2 - 2bc + 12ac .

If ∣ -a a^2 ab ac ab -b^2 bc ac bc -c^2 | = ka^2b^2c^2 , then k is equal to

If |(-a^2,ab,ac),(ab,-b^2,bc),(ac,bc,-c^2)|=lamdaa^2b^2c^2 then the value of lamda is :

|(b^(2)-ab,b-c,bc-ac),(ab-a^(2),a-b,b^(2)-ab),(bc-ac,c-a,ab-a^(2))|=

| [-bc, b ^ (2) + bc, c ^ (2) + bca ^ (2) + ac, -ac, c ^ (2) + aca ^ (2) + ab, b ^ (2) + ab, -ab (ab + bc + ac), is = 64. then

|(-a^(2),ab,ac),(ab,-b^(2),bc),(ac,bc,-c^(2))|=
