Call the unknown number n. From the problem statement (n + 3)2 - (n + 2)2 = 11. Expanding both squares yields n2 + 6 n + 9 - (n2 + 4n + 4) = 11, or 2 n + 5 = 11, 2n = 6, n = 3.

if it is not this . -3<x<-2 < or equal
Are you asking me to tell you the answer? Because its easy and simple .
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
2 x n(squared) + 2
More. 4 squared = 16 4.1 squared = 16.81 any number greater than 4 when squared is larger
If you mean: (x+3) squared = (x+2) squared +11 Then the value of x works out as 3
