`a^2` -2ab + `b^2` = ___

(a-b) (a^2 + ab + b^2) =____

(a - b)^2 + 4ab = ___

Factorise the following : a^3 - a^2b^2 - ab + b^3 .

Factorise a ^(3) - 3a^(2) b + 3ab ^(2) -b ^(3)

sqrt(4ab - 2i (a^(2) - b^(2) ) =

Prove that {:[( a^(2) , bc, ac+c^(2)),( a^(2) +ab,b^(2) ,ac),( ab,b^(2) +bc,c^(2)) ]:} =4a^(2) b^(2) c^(2)

Subtract the second expression from the first expression: 3a^2-8ab-2b^2 , 3a^2-4ab+6b^2

If A=[(ab,b^(2)),(-a^(2),-ab)] then A^(2)=

Factorise the expressions - 4ab - 2ab^(2) + 6ac - 2a^(2)b
