Question

which number should be added to 3 square + 2 square to get 3 + 2 whole square

Answer 1

Let added number be x

x+3²+2²=(3+2)²
x+9+4=9+4+12
x+13=25
x=25-13
x=12

To verify

12+9+4=25
25=25

Answer 2

let the number be x

A.T.S.

3^2 +2^2+x=(3+2)^2

9+4+x=5^2

13+x=25

x=25-13

x=12

So, the number is 12
