(2+2b+1)^2

its in the form of (a+b+c)^2

we can use this formula

=> (a+b+c)^2 = a^2 +b^2 + c^2 +2ab +2bc +2ca

a= 2 ,b= 2b ,c=1

2^2 +(2b)^2 + 1^2 +2(2×2b) +2(2b×1) +2(1×2)

4 + 4b^2 + 1 + 2(4b) + 2(2b) + 2(2)

4 +4b^2 + 1 + 8b + 4b + 4

9 + 4b^2 + 12b +

4b^2 + 12b + 9

(2b)^2 + 2×2b×3 + (3)^2

its in the form of a^2 + 2ab + b^2 = (a+b)^2

a = 2b , b = 3

(2b+3)^2 is the answer
