if i'm a two digit number then i'm 10a+b, so the difference of my square and 2*myself is:

(10a+b)2-2*(10a+b)

TTFN,

1*1-2 = -1
2*2-4 = 0
3*3-6 = 3
4*4 -8 = 8
5*5 -10 = 15
6*6-12 = 24

5 might be the first answer, If I correctly translated you version of English.

x*x - 2x > 10

I get 5 for the first integer for which the difference between its square and twice its value is a two digit number. Please write your questions in English as understood by older Americans.
