I assume you want to expand it.
(a+b)² = a² + 2ab + b²
(x+1)² = x² + 2x + 1² = x² + 2x + 1
2(x+1)² + 1
= 2(x² + 2x + 1) + 1
= 2x² + 4x + 2 + 1
= 2x² + 4x + 3

PEMDAS...
Please Exxcuse My Dear Aunt Sally...
BEDMAS...
parentheses, exponents, multiplication, division, addition, subtraction
That is the order of operations...
1. parentheses
2. exponents
(x+1)^2 = x^2 +2x +1
3. multiplication/division
2( x^2 +2x +1) = 2x^2 +4x +2
4. addition/subtraction
2x^2 +4x +2 +1
2x^2 + 4x +3
that is all I could think to do... I don't know what you wanted me to do...

2(x+1)^2+1= 2x+2^2+1= 2x+4+1= 2x+5
Its just basic distribution that's all.
But never add a variable or # with anything if it isn't a like term.

(2x+2)^2+1
but if you want a whole number you would need to find x
