13 + -2x + 2x2 = -10 + 10 + 5x2 + -5x2

Combine like terms: -10 + 10 = 0
13 + -2x + 2x2 = 0 + 5x2 + -5x2
13 + -2x + 2x2 = 5x2 + -5x2

Combine like terms: 5x2 + -5x2 = 0
13 + -2x + 2x2 = 0

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

Divide each side by '2'.
6.5 + -1x + x2 = 0

Move the constant term to the right:

Add '-6.5' to each side of the equation.
6.5 + -1x + -6.5 + x2 = 0 + -6.5

Reorder the terms:
6.5 + -6.5 + -1x + x2 = 0 + -6.5

Combine like terms: 6.5 + -6.5 = 0.0
0.0 + -1x + x2 = 0 + -6.5
-1x + x2 = 0 + -6.5

Combine like terms: 0 + -6.5 = -6.5
-1x + x2 = -6.5

The x term is -1x.  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 = -6.5 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -6.5 + 0.25

Combine like terms: -6.5 + 0.25 = -6.25
0.25 + -1x + x2 = -6.25

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -6.25

Can't calculate square root of the right side.

The solution to this equation could not be determined.
