If you mean: (x+3)^2 = (x+2)^2 +13 Then the value of the number x works out as 4
5+3^2-1 = 13 (5+3)^2-1=63
7^2 + 3^2 = 58
4x2 + 1 + x2 + 3 = 5x2 + 4
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
If you mean: (x+3) squared = (x+2) squared +11 Then the value of x works out as 3
104
9 is the value of -3 squared

5+3^2-1 = 13 (5+3)^2-1=63
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
3 squared is 3 x 3 or 9.
1 squared (1x1) +3=4
9 plus 16=25 3 squared is the same as 3 times three and 4 squared is the same as 4 times 4 3 times 3 + 4 times 4 9 plus 16 = 25
