2a ( a² + a - 2) + 8

When a = 2

= 2(2) [(2)² + 2 - 2)] + 8

= 4 ( 4 + 2 - 2) + 8

= 4 (4) +8

= 16 +8

= 24

Answer:

We will get the value is 24.

Step-by-step explanation:

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

         Given data:- a=2.

         To find:- Value of 2a(a^{2} +a-2)+8.

         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 a=2 in the given data we get,

          2a(a^{2} +a-2)+8\\=2(2)(2^{2} +2-2)+8\\=4(4+2-2)+8\\=4(6-2)+8\\=4(4)+8\\=16+8\\=24

 The question is to find the value of (a^{2} +a-2)+8 when a=2.
