Answer 2

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

             Given data:- $x=1.$

             To find:- Value of above expression $x(x-1)+2.$

             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 $x=1.$ and  in the given equation we get,

             $x(x-1)+2\\=1(1-1)+2\\=1(0)+2\\=0+2\\=2.$

     Hence we will get the value $x(x-1)+2=2.$
