Answer 2

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

          Given data:- $x=2,$ and $y=-3.$

          To find:- Value of above expression $x^{2} +4xy+y^{2} .$

          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 values x, and y  in the given equation we get,

            $x^{2} +4xy+y^{2} \\\Rightarrow (2)^{2} +4(2)(-3)+(-3)^{2} \\\Rightarrow 4+(-24)+(-3)^{2} \\\Rightarrow -11.$

 

         Hence we will get the value $-11.$
