Answer 2

Answer:

We will get the value is 57.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

       Given data:- $x=-2.$

       To find:- Value of $3x(2x-4)+x^{2} +5.$

       Solution:-

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

• BODMAS is an order of mathematic operations.

• It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

     Now put the value of x=-2 in $3x(2x-4)+x^{2} +5.$

       $3x(2x-4)+x^{2} +5\\=3(-2)(2(-2)-4)+(-2)^{2} +5\\=-6(-4-4)+4+5\\=-6(-8)+9\\=48+9\\=57$
