Simplifying
x2 + x + 2 + x + 2 = 100

Reorder the terms:
2 + 2 + x + x + x2 = 100

Combine like terms: 2 + 2 = 4
4 + x + x + x2 = 100

Combine like terms: x + x = 2x
4 + 2x + x2 = 100

Solving
4 + 2x + x2 = 100

Solving for variable 'x'.

Reorder the terms:
4 + -100 + 2x + x2 = 100 + -100

Combine like terms: 4 + -100 = -96
-96 + 2x + x2 = 100 + -100

Combine like terms: 100 + -100 = 0
-96 + 2x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '96' to each side of the equation.
-96 + 2x + 96 + x2 = 0 + 96

Reorder the terms:
-96 + 96 + 2x + x2 = 0 + 96

Combine like terms: -96 + 96 = 0
0 + 2x + x2 = 0 + 96
2x + x2 = 0 + 96

Combine like terms: 0 + 96 = 96
2x + x2 = 96

The x term is 2x.  Take half its coefficient (1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
2x + 1 + x2 = 96 + 1

Reorder the terms:
1 + 2x + x2 = 96 + 1

Combine like terms: 96 + 1 = 97
1 + 2x + x2 = 97

Factor a perfect square on the left side:
(x + 1)(x + 1) = 97
