Question

The value of (a+b)^2-(a-b)^2 is​

Answer 1

thae value of (a+b)^2-(a-b)^2

= 4ab

Answer 2

• We have to evaluate the above expression by using the given data.

               Given data:-$(a+b)^{2} -(a-b)^{2} .$

               To find:- Value of above expression.

               Solution:-

• To solve the above equation we will follow the BODMAS rule.  

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

     B= bracket

      O= order of power or rules

      D= division

      M= multiplication

      A= addition

      S=subtraction

      Therefore,

         $(a+b)^{2} -(a-b)^{2} \\\Rightarrow a^{2} +b^{2} +2ab-a^{2} -b^{2}+2ab\\\Rightarrow 2ab+2ab\\\Rightarrow 4ab.$

     Hence we will get $(a+b)^{2} -(a-b)^{2} =4ab.$
