`a ^(2) b^(2) - 6abc + 9c ^(2)`

Factories: 9 + 6z + z^(2)

Factories: 36 a ^(2) + 36a+9

Factories: x ^(2) +6ax+9a ^(2)

Factories: 1 - 6x + 9x ^(2)

Factorise : 12abc -6a^(2) b^(2) c^(2) + 3a^(3) b^(3) c^(3)

Factorise (a-2b-3c)(6bc-2ab-3ac)-6abc

If a+b+c=0 and omega,omega^(2) are imaginary cube roots of unity,then (a+b omega+c omega^(2))^(2)+(a+b omega^(2)+c omega)^(3)=3abc (b) 6abc (c) 9 abc (d) 27 abc

18a^2b^2 c/ (-6abc) = _____

If a+b+c=0 and omega,omega^2 are imaginary cube roots of unity, then (a+bomega+comega^2)^2+(a+bomega^2+comega)^3= 3abc (b) 6abc (c) 9 abc (d) 27 abc

Factories the following : (a+b)^(2) + 9(a+b) + 18
