Question

(a+b)²-(a-b)² if a=2&b=2 with steps​

Answer 1

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

               Given data:-$a=2,b=2.$

               To find:- Value of above expression $(a+b)^2-(a-b)^2.$

               Solution:-

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

• BODMAS is an order of mathematic operations.

• 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

    Now put the value a and b in the given equation we get,

            $(a+b)^2-(a-b)^2\\=>(2+2)^2-(2-2)^2\\=>(4)^2-0\\=>16$

     Hence we will get the value is $16.$
