`(a+b)^2-(a-b)^2`

(a+2b)^2-(a-2b)^2 is equal to: (a+2b)^2-(a-2b)^2 का मान है :

Simplify each of the following algebraic expressions: (a^2+b^2+2a b)+(a^2+b^2-2a b) (a^2+b^2+2a b)-(a^2+b^2-2a b)

Simplify each of the following algebraic expressions: (i) (a^2+b^2+2a b)+(a^2+b^2-2a b) (ii) (a^2+b^2+2a b)-(a^2+b^2-2a b)

If 2(a^2+b^2)=(a+b)^2 then, find the relation between a and b यदि 2(a^2+b^2)=(a+b)^2 तब

If vec a and vec b are two vectors,then prove that (vec a xxvec b)^(2)=a^(2)b^(2)-(a.b)^(2)

Simplify the (a^2+b^2)(a^2-b^2)+(b^2+c^2)(b^2-c^2)+(c^2+a^2)(c^2-a^2)

Factorise : a^(2) - b^(2) - (a+b)^(2)
