Reorder the terms:
2 + x = 100 + x2

Solving
2 + x = 100 + x2

Solving for variable 'x'.

Reorder the terms:
2 + -100 + x + -1x2 = 100 + x2 + -100 + -1x2

Combine like terms: 2 + -100 = -98
-98 + x + -1x2 = 100 + x2 + -100 + -1x2

Reorder the terms:
-98 + x + -1x2 = 100 + -100 + x2 + -1x2

Combine like terms: 100 + -100 = 0
-98 + x + -1x2 = 0 + x2 + -1x2
-98 + x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-98 + x + -1x2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
98 + -1x + x2 = 0

Move the constant term to the right:

Add '-98' to each side of the equation.
98 + -1x + -98 + x2 = 0 + -98

Reorder the terms:
98 + -98 + -1x + x2 = 0 + -98

Combine like terms: 98 + -98 = 0
0 + -1x + x2 = 0 + -98
-1x + x2 = 0 + -98

Combine like terms: 0 + -98 = -98
-1x + x2 = -98

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = -98 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -98 + 0.25

Combine like terms: -98 + 0.25 = -97.75
0.25 + -1x + x2 = -97.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -97.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
