2 + 3x = 6 + x2

Solving for variable 'x'.

Reorder the terms:
2 + -6 + 3x + -1x2 = 6 + x2 + -6 + -1x2

Combine like terms: 2 + -6 = -4
-4 + 3x + -1x2 = 6 + x2 + -6 + -1x2

Reorder the terms:
-4 + 3x + -1x2 = 6 + -6 + x2 + -1x2

Combine like terms: 6 + -6 = 0
-4 + 3x + -1x2 = 0 + x2 + -1x2
-4 + 3x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-4 + 3x + -1x2 = 0

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

Divide each side by '-1'.
4 + -3x + x2 = 0

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -3x + -4 + x2 = 0 + -4

Reorder the terms:
4 + -4 + -3x + x2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -3x + x2 = 0 + -4
-3x + x2 = 0 + -4

Combine like terms: 0 + -4 = -4
-3x + x2 = -4

The x term is -3x.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3x + 2.25 + x2 = -4 + 2.25

Reorder the terms:
2.25 + -3x + x2 = -4 + 2.25

Combine like terms: -4 + 2.25 = -1.75
2.25 + -3x + x2 = -1.75

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = -1.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
