Answer 2

• As per the data given in the question, we have to solve the algebraic identities.

      Given data:- $(a+b)(a-b).$

       To find:- Solve algebraic identities.

       Solution:-

• As we observe the given identity holds for every value of its variables, then we will put the value in one side of the equality with the other side.

• Where $a\ and \ b$ are constants. and $x$ is variables.

      The expansion of algebraic identities are

         $\Rightarrow (a+b)(a-b)\\=a^{2} -ab+ab-b^{2} \\=a^{2} -b^{2}.$
