            The problem in the post was formulated INACCURATELY,  and a question was absent at all.

            According to the rules of the forum,  I should IGNORE such a post.

            The correct formulation,  including a question,  is   THIS:


    When the sum of a number and 3 is squared, it is 9 more than the sum of the number and 2 when squared. Find the number.


                It is an ACCURATE,  CONSISTING and a POLITE form of the post.



Solution

%28x%2B3%29%5E2 - %28x%2B2%29%5E2 = 9     <<<---=== it is given


x%5E2+%2B+6x+%2B+9+-+x%5E2+-+4x+-+4 = 9


2x = 4


x = 2.

Solved.
